[0002] The continuous reaction method of halogenated hydrocarbons is very important in organic synthesis, especially in the formation of new carbon-carbon bonds. Transition metal-catalyzed coupling reactions are one of the effective methods for constructing carbon-carbon bonds, among which palladium-catalyzed coupling reactions are particularly favored because of their mild reaction conditions and excellent efficiency.

[0003] The existing continuous extraction of 2-chloropropane by halogenated hydrocarbons has limited extraction efficiency, so we designed a method for continuous collection of 2-chloropropane by halogenated hydrocarbons;

[0004] When continuously extracting 2-chloropropane, hydrogen chloride and isopropanol need to be injected into the enameled reactor in equal proportions. The flow rate needs to be controlled according to the amount of solution inside the enameled reactor tower. However, hydrogen chloride and isopropanol are injected through two pipes. When the flow rate of one pipe changes, the change of the other pipe cannot be updated in time, which will cause the injection ratio to change. Therefore, we designed a control device.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a method for continuously collecting 2-chloropropane from halogenated hydrocarbons, comprising introducing hydrochloric acid solution and isopropanol into an enameled reactor, wherein the volume ratio of the hydrochloric acid solution and the isopropanol is 100:91, performing a reflux reaction, collecting crude 2-chloropropane, and collecting crude 2-chloropropane from the discharge layer of the enameled reactor after refluxing for two to five hours;

[0035] Hydrogen chloride and isopropanol are introduced into the enameled reactor through the flow control device M. The flow control device M ensures the introduction ratio of hydrogen chloride and isopropanol. When the introduction speed of hydrogen chloride is regulated, the introduction speed of isopropanol is adjusted at the same ratio, so that the device can adjust the flow rate in equal proportion.

[0036] The reflux reaction is continued; the crude 2-chloropropane is continuously collected from the top discharge layer of the enameled reactor; the crude 2-chloropropane is treated to obtain 2-chloropropane.

[0037] The temperature of the reflux reaction is controlled at 85°C to 87°C. When the reflux in the enameled reactor is less than 200 L / h, hydrogen chloride and isopropanol are introduced. The crude 2-chloropropane product is washed with water in the enameled water washing reactor and then introduced into the enameled distillation reactor. The washed crude 2-chloropropane product is rectified in the enameled distillation reactor to obtain the finished 2-chloropropane product.

[0038] Furthermore, isopropanol as a solvent has a relatively low boiling point of only 82.5° C., and the temperature of the reflux reaction needs to be controlled to be higher than 85° C. to stabilize the reflux reaction.

[0039] During operation, the stirring motor of the reactor on the enameled reactor is first turned on, and the hydrochloric acid solution and isopropanol are introduced into the enameled reactor at a volume ratio of 100:91 for reflux reaction. During the reflux reaction, the reflux flow rate is controlled at 220 L / h. At this time, the crude 2-chloropropane is collected at 50 L / h. Due to the continuous extraction of the material inside the enameled reactor, the reflux flow rate will gradually decrease. When the reflux is less than 200 L / h, hydrogen chloride and isopropanol are introduced into the enameled reactor, and the reflux flow rate of the reflux reaction is controlled to be above 220 L / h and the crude 2-chloropropane is continuously collected. The collected crude 2-chloropropane can be washed with water and distilled to obtain a finished product. During the washing process, the pH value of the solution is maintained between 5 and 7.

[0040] Example 2, reference Figure 2-10 , which is the second embodiment of the present invention. Different from the previous embodiment, the flow control device M includes a connecting mechanism 100 and a control mechanism 200 arranged on the connecting mechanism 100; the connecting mechanism 100 includes a first valve tube 101 and a second valve tube 102, and the first valve tube 101 and the second valve tube 102 are connected through a containing box 103; the control mechanism 200 includes a round box 201 arranged on the containing box 103, a conduction component 202 arranged in the round box 201, and a movable component 203 arranged on the conduction component 202.

[0041] Specifically, the setting of the connecting mechanism 100 can effectively limit the material inside it, the setting of the first valve tube 101 and the second valve tube 102 can control the flow conditions inside it, the setting of the accommodating box 103 can effectively protect the valve bodies in the first valve tube 101 and the second valve tube 102, the setting of the round box 201 is convenient for better protecting the conduction component 202 and the movable component 203 inside it, the setting of the conduction component 202 can effectively connect the first valve tube 101 with the second valve tube 102, and the setting of the movable component 203 can effectively control the movable component 203, so as to select whether to enable the movable component 203 according to needs.

[0042] The transmission component 202 includes a first wheel body 202a and a second wheel body 202b respectively arranged on the first valve tube 101 and the second valve tube 102, a belt 202c is arranged between the first wheel body 202a and the second wheel body 202b, a built-in limiting column 202d and a reset ring 202e are arranged on the inner side of the first wheel body 202a, and an external ring 202f is arranged on the outer side of the reset ring 202e, the built-in limiting column 202d is slidably connected to the first wheel body 202a, the sliding stroke of the built-in limiting column 202d is less than one centimeter, the cross-section of the built-in limiting column 202d is circular, the built-in limiting column 202d is fixedly connected to the reset ring 202e, and the reset ring 202e The reset ring 202e is made of elastic material, and moves under the action of external pressure. During the contraction of the reset ring 202e, the built-in limit column 202d will be driven to move until it moves to the limit position of the moving stroke of the built-in limit column 202d. The inner wall of the external ring 202f is fixedly connected with a clamping seat 202g, and the reset ring 202e is located at the bottom of the inner side of the external ring 202f. The upper and lower ends of the external ring 202f are both in contact with the inner wall of the first wheel body 202a, and the outer wall of the external ring 202f is in contact with the inner wall of the belt 202c. Docking grooves 202h are provided on both sides of the clamping seat 202g. The setting of the docking grooves 202h facilitates better contact with the outer claws 202m. The built-in limiting column 202d is slidably connected to the first wheel body 202a. There are multiple built-in limiting columns 202d, which are distributed in a ring array between the reset ring 202e and the inner wall of the first wheel body 202a. The reset ring 202e is fixedly connected to the built-in limiting column 202d.

[0043] Furthermore, the configuration of the first wheel body 202a and the second wheel body 202b can effectively control the flow of the corresponding first valve tube 101 and the second valve tube 102, the configuration of the belt 202c can effectively connect the first wheel body 202a and the second wheel body 202b, the configuration of the clamping seat 202g facilitates better adaptation of the outer claw 202m, and during operation, the second wheel body 202b can be driven to rotate while the first wheel body 202a is rotated, and the configuration of the built-in limit column 202d can effectively limit the reset ring 202e.

[0044] The conducting component 202 further comprises a mounting groove 202i disposed on the first wheel body 202a, a positioning column 202j is disposed on the inner wall of the mounting groove 202i, a bracket 202k is sleeved on the outside of the positioning column 202j, and the bracket 202k has inner claws 202l and outer claws 202m on both sides, the mounting groove 202i is provided with a contact surface 202n and a receiving surface 202o corresponding to the inner claw 202l, and the outer claw 202m is adapted to the docking groove 202h. The positioning column 202j is connected to the mounting groove 202i through a torsion spring, and the number of the positioning columns 202j is multiple, and the multiple positioning columns 202j are distributed in the mounting groove 202i in a ring array, and a gap is provided between the positioning column 202j and the bracket 202k.

[0045] Among them, the installation groove 202i is located in the middle of the first wheel body 202a, and the cross-section of the installation groove 202i is annular. The setting of the installation groove 202i can effectively limit the positioning column 202j. The setting of the bracket 202k can drive the first wheel body 202a to rotate during the rotation of the second wheel body 202b. When the second wheel body 202b rotates, the flow of the first valve tube 101 at the bottom of the first wheel body 202a can be effectively adjusted. The setting of the outer claw 202m can effectively drive the inner claw 202l to enter the docking groove 202h.

[0046] The rest of the structure is the same as that of Example 1.

[0047] When the flow rates of the first valve tube 101 and the second valve tube 102 need to be adjusted simultaneously, in order to avoid the situation where the flow rate of the other side is maintained at the same level when the valve body on one side is adjusted;

[0048] First, the driving ring 203h on the movable component 203 is rotated, so that the movable component 203 tensions the belt 202c. The belt 202c is in a tensioned state under the limiting effect of the movable component 203. The second wheel body 202b on the second valve tube 102 is rotated. The second wheel body 202b drives the second valve tube 102 to rotate during the rotation of the second wheel body 202b, thereby adjusting the flow inside the second valve tube 102.

[0049] At the same time, the second wheel body 202b rotates, and the belt 202c is driven to rotate during the rotation of the second wheel body 202b. At this time, the belt 202c squeezes the external ring 202f on the first wheel body 202a, causing the external ring 202f to deform, thereby driving the reset ring 202e to move and deform at the same time. The clamping seat 202g moves toward the direction of the outer claw 202m under the action of the reset ring 202e. When the belt 202c rotates, the external ring 202f is driven to rotate. During the rotation of the external ring 202f, the clamping seat 202g is driven to rotate. During the rotation of the clamping seat 202g, the outer claw 202m is driven to move. After the outer claw 202m is resisted, it drives the bracket 202k to rotate. During the rotation of the bracket 202k, the inner claw 202l is driven to contact the accommodating surface 202o. The inner claw 202l applies force to drive the first wheel body 202a to rotate. During the rotation of the first wheel body 202a, the valve of the first valve pipe 101 is driven to rotate, thereby changing the valve flow.

[0050] In summary, the setting of the belt 202c can effectively connect the first wheel body 202a and the second wheel body 202b, and drive the belt 202c to rotate during the rotation of the second wheel body 202b, so that the first wheel body 202a can follow the rotation during the rotation of the second wheel body 202b, avoiding a large flow difference between the first wheel body 202a and the second wheel body 202b. During use, the second wheel body 202b drives the first wheel body 202a to rotate to ensure a certain degree of twisting, which makes it difficult to accurately grasp the specific flow of the valve body. When the movable component 203 fails, the valve bodies corresponding to the first wheel body 202a and the second wheel body 202b are in an independent state, and the flow can be accurately adjusted as needed.

[0051] Example 3, reference Figures 2 to 10 , which is the third embodiment of the present invention. Different from the previous embodiment, the movable component 203 includes a sliding groove 203a and a guide groove 203b arranged inside the round box 201, a reset belt 203c is provided at the center of the sliding groove 203a, both ends of the reset belt 203c are fixedly connected with a slide seat 203e, a slide cylinder 203d is provided on the top of the slide seat 203e, and a pull rope 203f is provided at the end of the slide seat 203e away from the reset belt 203c. The pull rope 203f is limited in the round box 201 by a guide frame 203g, and a swivel 203h is provided on the outside of the pull rope 203f.

[0052] Furthermore, the groove depth of the sliding groove 203a is not less than five millimeters, the reset belt 203c is located at the top center of the sliding groove 203a, the reset belt 203c is woven from elastic fibers, both ends of the sliding seat 203e are arc-shaped, the top of the sliding seat 203e is rotatably connected to the slide cylinder 203d, the pull rope 203f is rotatably connected to the sliding seat 203e, the slide cylinder 203d is located inside the belt 202c wheel, both sides of the guide groove 203b are arc-shaped, the pull rope 203f is located inside the guide groove 203b, the inner wall of the swivel 203h is fixedly connected to the pull rope 203f, and the outer wall of the slide cylinder 203d is in contact with the inner wall of the guide frame 203g.

[0053] There are two guide grooves 203b, which are located on both sides of the inner wall of the round box 201. Both sides of the guide groove 203b are arc-shaped. The guide frame 203g is located at the center between the sliding groove 203a and the guide groove 203b, and the sliding seat 203e is slidably connected to the sliding groove 203a.

[0054] The rest of the structure is the same as that of Example 2.

[0055] When in use, the swivel 203h is rotated, and the pull rope 203f is driven to move during the rotation of the swivel 203h. A slight angular deviation will occur in the movement of the pull rope 203f. At this time, the inner wall of the clamping seat 202g is in contact with the outer wall of the pull rope 203f. The pull rope 203f drives the slide 203e to move under the limiting action of the clamping seat 202g. The two slides 203e located in the sliding groove 203a move toward the end away from the reset belt 203c at the same time. The reset belt 203c stretches and accumulates elastic potential energy. The belt 202c is tightened during the movement of the slide 203e, so that the inner wall of the belt 202c drives the external movement to fit the outer wall of the outer claw 202m.

[0056] In summary, the setting of the slide 203e and the sliding groove 203a facilitates better limiting the slide 203d. During the operation, the outer wall of the slide 203d fits against the inner wall of the belt 202c. During the movement of the slide 203d, the middle part of the belt 202c can be effectively driven to move to both sides. The setting of the pull rope 203f can effectively drive the slide 203e to move. When the swivel 203h is rotated, the pull rope 203f will follow the movement, thereby driving the slide 203e and the slide 203d to move. During the movement of the slide 203d, the belt 202c can be effectively tensioned.
