Description

[Technical field]

[0001] The present invention relates to a generating device and a generating method. [Background technology]

[0002] In recent years, metal-organic frameworks (MOFs) have been attracting attention as one of the substance adsorbents. Metal-organic complexes, also called metal-organic frameworks, metal-organic frameworks, or porous coordination polymers (PCPs), are porous materials that can be produced from metal salts and organic compounds as raw materials. Metal-organic complexes have a highly regular lattice structure formed by metal ions and organic ligands with lattice spacing on the order of nanometers, and are known to have functions such as storage, separation, and catalytic reactions of substances. Compared to other conventionally known porous materials such as activated carbon, which is a graphite-based carbon material, and zeolites, which are mainly composed of silicon and aluminum, metal-organic complexes have a very large surface area and have a unique substance adsorption performance that allows the chemical environment in the pores to be designed.

[0003] As a method for producing an organometallic complex, for example, a solvothermal method and an autoclave method have been considered. The solvothermal method and the autoclave method are batch synthesis methods in which a plurality of liquid materials are reacted in a vessel heated and pressurized to a predetermined temperature and pressure. Using the solvothermal method and the autoclave method, a liquid material containing a metal salt and a liquid material containing an organic compound are reacted in a vessel heated and pressurized to a predetermined temperature and pressure, thereby producing an organometallic complex. For example, Patent Document 1 discloses a method for synthesizing zinc-based metal-organic frameworks (Zn-MOFs) by a solvothermal method. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-22982 Summary of the Invention [Problem to be solved by the invention]

[0005] As in the technology described in Patent Document 1, by using a batch-type synthesis method such as a solvothermal method and proceeding with the reaction in a relatively large vessel, it is possible to produce organometallic complexes on a large scale, thereby improving productivity. However, when the batch-type synthesis method described in Patent Document 1 is performed in a vessel with a large reaction space for solution synthesis, it is likely that unevenness in the concentration of the liquid material supplied into the vessel and unevenness in the temperature and pressure in the vessel will occur. As a result, it is thought that there is a possibility that the size (particle diameter) of the generated organometallic complex will be easily varied. It is thought that such a problem occurs not only when generating an organometallic complex, but also generally when generating a reaction product by the reaction of liquid materials with each other.

[0006] Therefore, an object of the present invention is to provide an apparatus and method for producing a reaction product that can suppress variation in particle size of the reaction product. [Means for solving the problem]

[0007] A generation apparatus according to one embodiment of the present disclosure includes a plurality of material supply units that supply liquid material toward a single reaction space, a plurality of pumps that pump liquid material to each of the material supply units, a recovery unit that recovers reaction products produced by reactions between the liquid materials supplied from each of the material supply units, and an air injection unit that injects air toward the reaction space to blow the reaction products produced in the reaction space toward the recovery unit.

[0008] A method for generating reaction products according to one embodiment of the present disclosure includes supplying a plurality of liquid materials toward a single reaction space, injecting air toward the reaction space to blow away reaction products generated in the reaction space by reactions between the liquid materials, and collecting the blown-away reaction products. Effect of the Invention

[0009] According to the present invention, there is provided an apparatus and method for producing a reaction product that can suppress variation in particle size of the reaction product. [Brief description of the drawings]

[0011] Hereinafter, the present embodiment will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same reference numerals are used as much as possible for the same components in each drawing, and duplicated description will be omitted. In addition, each drawing may show an X-axis, a Y-axis, and a Z-axis. The X-axis, the Y-axis, and the Z-axis form a right-handed three-dimensional Cartesian coordinate system. Hereinafter, the arrow direction of the X-axis will be called the +X direction, and the direction opposite to the arrow will be called the -X direction. The same applies to the other axes. In addition, the +Z direction may be called the "upper side" or "upward", and the -Z direction may be called the "lower side" or "downward". In addition, a plane perpendicular to the X-axis, Y-axis, or Z-axis may be called the YZ plane, the ZX plane, or the XY plane. However, these directions are used for convenience to explain the relative positional relationship. Therefore, these directions do not define the absolute positional relationship.

[0012] (Reaction product generating device) The reaction product generating apparatus 100 according to an embodiment of the present disclosure will be described below. In the following, an example will be described in which a metal salt is reacted with an organic compound using the reaction product generating apparatus 100 to generate an organometallic complex (Metal-Organic Framework (MOF)) as a reaction product.

[0013] 1 is a front view showing a schematic configuration of a generating apparatus 100 according to an embodiment of the present disclosure. As shown in FIG. 1, the generating apparatus 100 includes a plurality of material supply units 110, a plurality of pumps 120, a recovery unit 130, and an air injection unit 140.

[0014] The multiple material supply units 110 supply liquid materials toward one reaction space. The material supply units 110 include a first material supply unit 110a and a second material supply unit 110b. The first material supply unit 110a supplies a first liquid material 152a toward the reaction space M1. The second material supply unit 110b supplies a second liquid material 152b toward the reaction space M1. In the generating apparatus 100 according to the present embodiment, the first material supply unit 110a includes a first nozzle 112a configured to spray the first liquid material 152a, and the second material supply unit 110b includes a second nozzle 112b configured to spray the second liquid material 152b. In this embodiment, the reaction space M1 is a space including a confluence point where the first liquid material 152a supplied from the first nozzle 112a of the first material supply unit 110a and the second liquid material 152b supplied from the second nozzle 112b of the second material supply unit 110b confluence, and is a region including the intersection point of the central axis of the flow path in the first nozzle 112a and the central axis of the flow path in the second nozzle 112b, as described below.

[0015] The multiple pumps 120 include a first pump 120a and a second pump 120b. The first pump 120a is connected to the first liquid material storage section 150a via a first supply pipe 160a. The first pump 120a sends out the first liquid material 152a stored in the first liquid material storage section 150a to the first material supply section 110a. The second pump 120b is connected to the second liquid material storage section 150b via a second supply pipe 160b. The second pump 120b sends out the second liquid material 152b stored in the second liquid material storage section 150b to the second material supply section 110b. As the first pump 120a and the second pump 120b, a non-pulsating (non-pulsating flow) pump may be used. By using non-pulsating pumps as the first pump 120a and the second pump 120b, the first liquid material 152a and the second liquid material 152b can be supplied at a constant flow rate, so that the first liquid material 152a and the second liquid material 152b can react with each other without excess or deficiency. For example, a mono pump may be used as the non-pulsating pump. Alternatively, a pump with pulsating flow that has been improved to have a non-pulsating flow may be used as the non-pulsating pump. In addition, a pump with pulsation (pulsating flow) may be used as the first pump 120a and the second pump 120b, and for example, a plunger pump or a gear pump with pulsating flow may be used.

[0016] The recovery section 130 recovers a reaction product 190 produced by a reaction between the liquid materials (first liquid material 152a and second liquid material 152b) supplied from each material supply section 110 (first material supply section 110a and second material supply section 110b).

[0017] The air injection unit 140 injects air toward the reaction space M1, thereby blowing off the reaction product 190 generated in the reaction space M1 toward the recovery unit 130. In the generation apparatus 100 according to this embodiment, the air injection unit 140 includes an air injection nozzle 142 configured to inject air vertically downward (i.e., in the -Z direction). As shown in FIG. 1, the reaction space M1 is outside the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the injection opening 118b of the second nozzle 112b of the second material supply unit 110b, and exists downstream of the air injection nozzle 142, which is the air injection unit 140, in the direction in which the air injection nozzle 142 injects air (the -Z direction).

[0018] In the generating apparatus 100 according to this embodiment, the first material supply unit 110a, the second material supply unit 110b, and the air injection unit 140 are provided on a support member 170. The generating apparatus 100 according to this embodiment also includes a heating unit 180 (see FIG. 3) and the like. The heating unit 180 will be described later.

[0019] 2 to 4, the configuration of the material supply unit 110 and the air injection unit 140 of the production apparatus 100 will be described. Fig. 2, Fig. 3, and Fig. 4 are a perspective view of the support member 170, a front view seen from the +Y direction, and a bottom view seen from the -Z direction, respectively.

[0020] The support member 170 supports the first material supply unit 110a, the second material supply unit 110b, and the air injection unit 140, and has a rectangular parallelepiped shape as shown in FIG. 2. As shown in FIG. 2, FIG. 3, and FIG. 4, the support member 170 is provided with mounting units 172a, 172b, and 172c for mounting the first material supply unit 110a, the second material supply unit 110b, and the air injection unit 140 on the side surface (YZ surface) in the +X direction, the side surface (YZ surface) in the -X direction, and the top surface (XY surface) in the +Z direction, respectively. The mounting unit 172a and the mounting unit 172b are provided at the same height as seen in the Z direction, facing each other in the X direction. The first material supply unit 110a is disposed so that the injection opening 118a of the first nozzle 112a faces the -X direction with respect to the mounting unit 172a. Further, the second material supply unit 110b is disposed relative to the installation unit 172b such that the ejection opening 118b of the second nozzle 112b faces the +X direction. Therefore, the first material supply unit 110a and the second material supply unit 110b are disposed so as to face each other in the X direction. More specifically, the first material supply unit 110a and the second material supply unit 110b are disposed so that a straight line connecting the center of the opening 118a (the center in a cross section perpendicular to the X direction) and the center of the opening 118b is parallel to the X direction. Note that, although an example has been described here in which the straight line connecting the center of the opening 118a and the center of the opening 118b is parallel to the X direction, this is not limiting, and for example, the central axis of the flow channel of the first material supply unit 110a (axis perpendicular to the opening 118a) and the central axis of the flow channel of the second material supply unit 110b (axis perpendicular to the opening 118a) may be disposed so as to be inclined with respect to the X direction. For example, the central axis of the first material supply unit 110a and the central axis of the second material supply unit 110b may be inclined by ±10° with respect to the X-axis (axis extending in the X-direction).

[0021] In addition, a mixing space 174 is provided on the lower surface side in the -Z direction of the support member 170. The mixing space 174 is a space in which the first material 152a supplied from the first material supply unit 110a and the second material 152b supplied from the second material supply unit 110b react with each other. The mixing space 174 is provided so as to open downward (in the -Z direction) of the support member 170. As shown in FIG. 3, the upper surface (surface in the +Z direction) of the mixing space 174 is substantially semicircular with a convex shape on the upper side in a cross-sectional view (cross-section (XZ surface) perpendicular to the Y direction). Therefore, the inner surface on the upper side (in the +Z direction) of the mixing space 174 has a hemispherical surface provided so as to be convex on the upper side. As shown in FIG. 4, the opening 174a of the mixing space 174 is circular.

[0022] 5 shows a schematic diagram of the reaction that proceeds inside the support member 170. As shown in FIG. 5, the first liquid material 152a sent from the first material supply unit 110a in the -X direction and the second liquid material 152b sent from the second material supply unit 110b in the +X direction collide in a reaction space M1 including a junction where the first liquid material 152a and the second liquid material 152b join in the mixing space 174 of the support member 170. In this embodiment, the first liquid material 152a contains a metal salt, and the second liquid material 152b contains an organic compound. When the first liquid material 152a and the second liquid material 152b collide with each other, the metal salt in the first liquid material 152a reacts with the organic compound in the second liquid material 152b, and a substance that becomes the nucleus of an organometallic complex is generated as a reaction product. In the generating apparatus 100 according to this embodiment, air is injected in the -Z direction by the air injection unit 140 into the reaction space M1 in the mixing space 174. Therefore, the substance that will become the nucleus of the organometallic complex generated by the collision between the first liquid material 152a and the second liquid material 152b is blown away in the -Z direction. The substance that will become the nucleus of the organometallic complex is discharged in the -Z direction from the opening 174a of the mixing space 174 to the outside of the support member 170. The substance that will become the nucleus of the organometallic complex, which is the discharged reaction product, is collected by the collection unit 130 provided in the -Z direction of the support member 170.

[0023] The following describes the effects of the generating device 100 according to this embodiment.

[0024] Conventionally, various methods have been used as a method for generating a reaction product. For example, when a metal salt and an organic compound are reacted to generate an organometallic complex as a reaction product, for example, a solvothermal method, an autoclave method, etc. have been used. Using the solvothermal method or the autoclave method, a liquid material containing a metal salt and a liquid material containing an organic compound are reacted in a container heated and pressurized to a predetermined temperature and pressure, and an organometallic complex can be generated by a batch-type synthesis method. Since the solvothermal method and the autoclave method are batch-type, mass production is possible if the reaction is allowed to proceed in a relatively large space. However, at this time, since the mixing space in which the solution synthesis reaction is performed is large, unevenness in the concentration of the liquid material supplied into the container and unevenness in the temperature and pressure in the container are likely to occur. As a result, the size (particle diameter) of the generated organometallic complex may be easily varied. Therefore, depending on the batch-type generation method, it may be difficult to control the particle diameter.

[0025] In the generator 100 according to the present embodiment, the liquid materials 152a and 152b are supplied toward one reaction space M1 by the material supply units 110a and 110b, and air is injected toward the reaction space M1 by the air injection unit 140. As a result of intensive research, the inventors have been able to generate a reaction product of a more uniform size by injecting air into the reaction space M1 where the liquid materials 152a and 152b collide with each other by the air injection unit 140. When the reaction is performed by a batch method such as the solvothermal method or the autoclave method, the substances that become the cores of the organometallic complex, which is the reaction product generated by the collision of the liquid materials 152a and 152b, may further adhere to each other and become larger. However, in the generator 100 according to the present embodiment, the adhesion of the reaction products to each other can be suppressed by injecting air into the reaction space M1 where the reaction to generate the reaction product is performed, so that a reaction product of a more uniform size can be obtained.

[0026] Furthermore, in the generating apparatus 100 according to this embodiment, the first pump 120a and the second pump 120b can continuously supply the first liquid material 152a and the second liquid material 152b, respectively, so that the reaction product can be continuously generated. For example, in the above-mentioned solvothermal method and autoclave method, a relatively large amount of reaction product can be generated at once, but since they are batch-type, continuous generation is not possible. The generating apparatus 100 according to this embodiment, due to the above-mentioned configuration, can continuously generate the reaction product while improving productivity compared to the conventional method. In addition, it is also possible to suppress the variation in size of the generated reaction product.

[0027] In the generating apparatus 100 according to this embodiment, the first nozzle 112a of the first material supply unit 110a may be configured with a first pump 150a so as to inject the first liquid material 152a at a first flow rate which is a constant flow rate. Similarly, the second nozzle 112b of the second material supply unit 110b may be configured with a second pump 150b so as to inject the second liquid material 152b at a second flow rate which is a constant flow rate. The first flow rate and the second flow rate may be, for example, predetermined flow rates. At this time, the first liquid material 152a and the second liquid material 152b are supplied at a constant flow rate, so that they can react with each other without excess or deficiency. The first flow rate and the second flow rate are, for example, both 200 ml / 5 min (40 ml per minute). In other embodiments, the flow rate may not be constant. For example, the flow rate may be dynamically changed.

[0028] In this embodiment, the injection pressure at which the first liquid material 152a is injected from the first nozzle 112a and the injection pressure at which the second liquid material 152b is injected from the second nozzle 112b are both set to be greater than the injection pressure at which air is injected from the air injection unit 140. This makes it possible to prevent the first liquid material 152a and the second liquid material 152b from being blown away by the air injected by the air injection unit 140 before they collide with each other and react. The injection pressure at which the first liquid material 152a is injected and the injection pressure at which the second liquid material 152b is injected may be controlled by the first pump 150a and the second pump 152b, respectively.

[0029] In the generating device 100 according to this embodiment, the ejection opening 118a of the first nozzle 112a of the first material supply unit 110a and the ejection opening 118b of the second nozzle 112b of the second material supply unit 110b are spaced apart from each other with a distance of 0.05 mm or more and 1.0 mm or less (distance D1 shown in FIG. 6). FIG. 6 is a schematic cross-sectional view for explaining the relationship between the air ejection unit 140 and the first material supply unit 110a and the second material supply unit 110b. The distance D1 is the distance between the ejection opening 118a and the ejection opening 118b on a straight line connecting the central axis of the flow path in the nozzle 112a and the central axis of the flow path in the nozzle 112b. That is, as shown in FIG. 6, the distance D1 is the distance between the center of the ejection opening 118a and the center of the ejection opening 118b. The ejection opening 118a and the ejection opening 118b are, for example, circular. Therefore, the center of ejection opening 118a is the center of a circle in a cross section perpendicular to the X direction of ejection opening 118a, and the center of ejection opening 118b is the center of a circle in a cross section perpendicular to the X direction of ejection opening 118b.

[0030] If the distance D1 between the ejection opening 118a and the ejection opening 118b is less than 0.05 mm, the ejected liquid material 152a and / or the liquid material 152b, or the reaction product generated by the reaction between the liquid material 152a and the liquid material 152b, may scatter and adhere to the ejection opening 118a and / or the ejection opening 118b, causing clogging of the first nozzle 112a and / or the second nozzle 112b. By setting the distance between the ejection opening 118a and the ejection opening 118b to 0.05 mm or more, clogging of the nozzles (the first nozzle 112a and the second nozzle 112b) caused by the scattered liquid materials 152a, 152b, or the reaction product, etc. can be suppressed. In addition, by setting the distance between the first material supply unit 110a and the second material supply unit 110b to 1.0 mm or less, the first liquid material 152a and the second liquid material 152b can be more reliably reacted with each other. Therefore, the productivity of the production of the reaction product can be improved.

[0031] Furthermore, in the generating apparatus 100 according to this embodiment, the injection opening 148 of the air injection nozzle 142 of the air injection unit 140 may be spaced apart such that the distance (distance D2 shown in FIG. 6) from a straight line (straight line L1 shown in FIG. 6) connecting the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the injection opening 118b of the second nozzle 112b of the second material supply unit 110b is 0.1 mm or more and 10.0 mm or less.

[0032] In this embodiment, by joining the liquid materials 152 (first liquid material 152a and second liquid material 152b) in a relatively fine space, the number of nuclei of the generated reaction product (e.g., organometallic complex) is reduced, and the nuclei are blown away by air jet, thereby suppressing further crystal growth and adhesion to each other. This makes it possible to generate reaction products of relatively uniform size. Note that, for example, when there is relatively little need to reduce the number of nuclei, the space where the liquid materials 152 join together does not need to be a fine space.

[0033] In addition, in the generating device 100 according to this embodiment, the air injection unit 140 is disposed in a direction (+Z direction) perpendicular to a straight line (straight line L1 shown in FIG. 6) connecting the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the injection opening 118b of the second nozzle 112b of the second material supply unit 110b, and the injection direction of the air injection unit 140 is the -Z direction. Therefore, in FIG. 6, the angle θa between the injection direction of the injection opening 148 and the straight line L1 is 90°, but the arrangement of the air injection unit 140 is not limited to this. For example, the angle θa of the injection direction of the air with respect to the straight line L1 connecting the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the injection opening 118b of the second nozzle 112b of the second material supply unit 110b may be 45° or more and 135° or less.

[0034] Furthermore, in the generating apparatus 100 according to this embodiment, the aperture diameter of the ejection opening 118a of the first nozzle 112a of the first material supply unit 110a and the ejection opening 118b of the second nozzle 112b of the second material supply unit 110b may be, for example, 0.1 mm or more and 1.0 mm or less. Also, the ejection pressure of the first liquid material 152a of the first nozzle 112a of the first material supply unit 110a and the ejection pressure of the second liquid material 152b of the second nozzle 112b of the second material supply unit 110b may be, for example, 0.05 MPa or more and 1.00 MPa or less.

[0035] The distances between the components and the arrangement angles described above are merely examples and may be other sizes. They may also be changed as appropriate depending on the liquid material used, the environment in which they are used, the particle diameter of the reaction product produced, and the like. For example, the injection pressure of the air injection unit 140 may be changed depending on the target particle diameter of the reaction product or the target variation in particle diameter.

[0036] As described above, the generating device 100 according to this embodiment may further include a heating unit 180. As shown in Fig. 3, the heating unit 180 may be an electric heating coil, and may include, for example, a coil-shaped heating unit 180a provided around the first material supply unit 110a, a coil-shaped heating unit 180b provided around the second material supply unit 110b, and a coil-shaped heating unit 180c provided around the air injection unit 140.

[0037] For example, the first liquid material 152a sprayed from the first nozzle 112a of the first material supply unit 110a and the second liquid material 152b sprayed from the second nozzle 112b of the second material supply unit 110b may be sprayed toward the reaction space M1 after being heated by the heating unit 180a and the heating unit 180b, respectively. Also, the air sprayed from the air spray unit 140 may be sprayed toward the reaction space M1 after being heated by the heating unit 180c.

[0038] As illustrated in FIG. 3, the heating unit 180 may be provided for each of the first material supply unit 110a, the second material supply unit 110b, and the air injection unit 140, but is not limited thereto. Alternatively, the heating unit 180 may be provided for two or all of the air injection unit 140, the first material supply unit 110a, and the second material supply unit 110b. The heating unit 180 may be provided, for example, to heat the entire support member 170, or may be provided to heat, for example, the first supply pipe 160a or the second supply pipe 160b before each fluid is supplied to the support member 170. The heating unit 180 may be configured using, for example, an electric heating wire. The degree to which the liquid material 152 injected by the material supply unit 110 or the air injected by the air injection unit 140 is heated may be appropriately set according to, for example, the material to be reacted, the production amount, etc.

[0039] The nozzles (first nozzle 112a and second nozzle 112b) used in the air injection unit 140, the first material supply unit 110a, and the second material supply unit 110b are not particularly limited, and conventionally known nozzles can be used. As the nozzles used in the air injection unit 140, the first material supply unit 110a, and the second material supply unit 110b, for example, a straight nozzle or a conical nozzle can be used.

[0040] The jet nozzle 142 of the air injection unit 140 may be a nozzle in which the shape of the injected air (shape in a cross section perpendicular to the injection direction (shape in a cross section parallel to the XY plane in FIG. 1)) is rectangular. Such a nozzle is also called a slit-type air nozzle. The jet nozzle 142 of the air injection unit 140 may be a nozzle in which the shape of the injected air (shape in a cross section parallel to the XY plane) is circular. In this case, the injected air becomes cylindrical or conical straight-moving air. In either nozzle, the size of the jet nozzle and the injection pressure can be set appropriately based on the reaction products generated, the reaction rate, etc.

[0041] (Modification) Modified examples of the reaction product generating apparatus of this embodiment will be described with reference to Figures 7 to 9. The reaction product generating apparatus 100 described above has been described as having two material supply units 110 (first material supply unit 110a and second material supply unit 110b), but the number of material supply units 110 is not limited to this. For example, when a reaction product is generated using three or more liquid materials, three or more material supply units 110 may be provided.

[0042] FIG. 7 is a top view showing an enlarged schematic view of the reaction space M1 of the material supply unit 110A of the modified example. That is, FIG. 7 shows a top view of the material supply unit 110A of the modified example seen from the +Z direction. As shown in FIG. 7, the material supply unit 110A includes three material supply units, 110a1, 110a2, and 110a3. The material supply unit 110A is used when reacting three types of liquid materials 152. As shown in FIG. 7, the material supply units 110a1, 110a2, and 110a3 of the material supply unit 110A are arranged to form an angle of 120° with each other, for example. Therefore, the material supply units 110a1, 110a2, and 110a3 are arranged to be equidistant from each other when viewed in the circumferential direction of a circle centered around the reaction space M1. By arranging material supply units 110a1, 110a2, and 110a3 equally in this manner, in the supporting member 170 equipped with material supply unit 110A, three types of liquid materials can be caused to collide with each other under the same conditions and react with each other.

[0043] When three kinds of liquid materials are reacted, for example, in the same configuration as the generating device 100 according to the present embodiment having the two material supply units 110a and 110b described with reference to FIG. 1, it is also possible to eject a solution obtained by synthesizing two kinds of liquid materials from the first nozzle 112a and eject the remaining solution from the second nozzle 112b to cause the two kinds of liquid materials to react. However, in that case, before the solution obtained by synthesizing two kinds of liquid materials and the remaining solution collide with each other, a solid product generated by the reaction between the two kinds of solutions in the first nozzle may grow and become crystals inside the first nozzle 112a, causing the solution in the first nozzle 112a to become suspended and cause clogging. In contrast, by using three material supply units 110a1, 110a2, and 110a3 when reacting three kinds of liquid materials as in the material supply unit 110A of the modified example, it is not necessary to synthesize two kinds of solutions in advance, and clogging inside the material supply unit 110 can be suppressed. Therefore, the productivity of the reaction product using the three kinds of solutions can be improved.

[0044] As with the material supply unit 110A shown in FIG. 7, even when four or more types of liquid materials are used for reaction, the angle between the material supply units 110 may be adjusted depending on the number of material supply units 110. For example, multiple material supply units 110 may be equally arranged so as to form an angle calculated as 360° / number of nozzles (number of material supply units 110).

[0045] Fig. 8 is a top view of another modified material supply unit 110B, seen from the +Z direction. The material supply unit 110B is used when reacting four types of liquid materials 152. As shown in Fig. 8, the material supply unit 110B includes four material supply units 110b1, 110b2, 110b3, and 110b4, and the material supply units 110b1, 110b2, 110b3, and 110b4 are equally arranged at an angle of 90° to each other, for example.

[0046] 9 is a schematic diagram of a material supply unit 110C of yet another modified example. The material supply unit 110C is used when six types of liquid materials 152 are reacted. As shown in FIG. 9, the material supply unit 110C includes six material supply units 110c1, 110c2, 110c3, 110c4, 110c5, and 110c6, and the material supply units 110c1, 110c2, 110c3, 110c4, 110c5, and 110c6 are equally arranged at an angle of, for example, 60° to each other.

[0047] As another modified example, for example, when reacting five types of liquid materials 152, five material supply sections 110 may be equally arranged to form an angle of 72°, which is calculated by dividing 360° by the number of nozzles (five).

[0048] Even when three or more kinds of liquid materials are used for reaction, the air injection unit 140 injects air in the -Z direction toward the reaction space M1, thereby making it possible to control the particle size of the reaction product and improve productivity, as in the case of using two kinds of liquid materials. When two kinds of liquid materials are used, as described above, an air injection unit 140 in which the cross-sectional shape of the injected air flow is rectangular or circular may be used. Furthermore, when three or more material supply units 110 are used, it is preferable to use an air injection unit 140 in which the cross-sectional shape is circular (i.e., an air injection unit 140 in which the shape of the injected air is cylindrical (or conical)). By using the air injection unit 140 in which the cross-sectional shape is circular, for example, to inject air toward the liquid material 152 supplied to the reaction space M1 so that the center of the circle, which is the cross-sectional shape of the injected air flow, is near the center of the reaction space M1, it is possible to inject air at a relatively uniform injection pressure toward the liquid material 152 supplied from each material supply unit 110. Therefore, the reaction between the liquid materials 152 can proceed relatively uniformly.

[0049] An example of a generating device that can accommodate a plurality of different numbers of material supply units 110 will be described with reference to Figures 10 and 11. Figure 10 is a schematic top view (top view parallel to the XY plane) of a supporting member 170G of a generating device according to another embodiment in this case, as viewed from the +Z direction, and Figure 11 is a cross-sectional view (cross-sectional view parallel to the XZ plane) of the supporting member 170G as viewed from the +Y direction.

[0050] As shown in FIG. 10, the support member 170G has six nozzle mounting parts 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6 (hereinafter, the six nozzle mounting parts are also collectively referred to as nozzle mounting parts 172g). The nozzles of the material supply parts 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are arranged in the nozzle mounting parts 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6, respectively. The outer shape of the support member 170G is cylindrical. Therefore, as shown in FIG. 10, the outer shape of the support member 170G is circular in a top view, and as shown in FIG. 11, the outer shape of the support member 170G is rectangular (e.g., rectangular) in a cross section parallel to the XZ plane.

[0051] In the support member 170G, the material supply units 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are configured to be detachable. In the case shown in Fig. 10, the six material supply units 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are arranged on all six nozzle installation units 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6, respectively, to cause reactions by six types of liquid materials 152 to proceed. In the support member 170G, the nozzle mounting portions 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6 all have the same size and shape, and the material supply portions 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 also have the same size and shape.

[0052] For example, when the reaction is carried out using two kinds of liquid materials 152 described with reference to Fig. 1, etc., the two material supply units 110g1 and 110g4 can be installed and used only for the nozzle installation units 172g1 and 172g4 out of the six nozzle installation units 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6. In this case, it is preferable to block the unused nozzle installation units 172g2, 172g3, 172g5, and 172g6, since this can prevent the liquid materials from scattering and the adhesion of the generated reaction products.

[0053] 7, the three nozzle installation parts 172g1, 172g3, and 172g5 are provided with three material supply parts 110g1, 110g3, and 110g5, respectively, so that the three liquid materials can be reacted to generate a reaction product as a generating device. In this case, it is preferable to block the unused nozzle installation parts 172g2, 172g4, and 172g6.

[0054] As described with reference to Figs. 7 to 9, when three or more kinds of liquid materials are collided and reacted, the number of nozzles 112 of the material supply unit 110 increases, and the support member 170 is processed according to the number of nozzles 112, for example. As shown in Figs. 10 and 11, by making the nozzle installation parts 172g the same size and shape, and by making the size and shape of the material supply unit 110 the same, the material supply unit 110 can be unitized, and the nozzles 112 of the material supply unit 110 required according to the type of liquid material 152 to be reacted can be inserted into the nozzle installation part 172g and used, thereby making the support member 170G versatile. At this time, by making the overall outer shape cylindrical like the support member 170G, the nozzle installation parts 172g and the nozzles 112 of the material supply unit 110g can be arranged symmetrically with respect to the center point corresponding to the joining point where the liquid materials 152 join together in the reaction space M1.

[0055] The support member 170G described with reference to FIG. 10 and FIG. 11 has six nozzle installation parts 172g, which is particularly preferable when two, three, and six types of liquid materials 152 are reacted. However, as another modified example, for example, eight nozzle installation parts are provided at intervals of 45° from the center point near the reaction space M1, so that two, four, and eight types of liquid materials 152 can be mixed and reacted. The number of nozzle installation parts 172 is not limited to six or eight, and the nozzle installation parts 172 may be appropriately provided on the support member 170 according to the number of liquid materials that may be sprayed simultaneously. Then, among the provided nozzle installation parts 172, the nozzles 112 of the material supply part 110 may be arranged on the nozzle installation parts 172 according to the number of liquid materials to be reacted, and used to generate reaction products.

[0056] (Method of Producing Reaction Products) A method for producing a reaction product according to an embodiment of the present disclosure will be described with reference to Fig. 12. Fig. 12 is a flow chart of a method for producing a reaction product according to an embodiment of the present disclosure.

[0057] First, a plurality of liquid materials are supplied to one reaction space M1 (S1202).

[0058] Next, air is sprayed toward the reaction space M1 to blow away reaction products generated in the reaction space M1 due to the reaction between the liquid materials (S1204).

[0059] Next, the blown-off reaction products are collected (S1206).

[0060] As a result of the above, a reaction product is produced.

[0061] When an organometallic complex is generated using the reaction product generation apparatus and reaction product generation method according to this embodiment, for example, the core material of the organometallic complex is recovered from the suspension containing the core material of the organometallic complex recovered in recovery section 130 using a centrifuge or the like, and then dried and activated to obtain crystals of the organometallic complex.

[0062] The reaction product generating apparatus and the reaction product generating method according to the present embodiment can be used to generate various reaction products generated by reacting a plurality of liquid materials. In particular, they can also be used to generate organometallic complexes generated by the reaction of an organic compound with a metal salt. Examples of organometallic complexes that can be generated using the reaction product generating apparatus and the reaction product generating method according to the present embodiment include ZIFs, HKUSTs, ELMs, SIFSIXs, JASTs, and CPLs. In addition, the organometallic complexes generated by the reaction product generating apparatus and the reaction product generating method according to the present embodiment can be used as a filter that selectively separates a target substance by attaching it to a nonwoven fabric, for example.

The elements of the embodiments, as well as their arrangements, materials, conditions, shapes, sizes, etc., are not limited to those shown as examples and can be changed as appropriate.
