Description

Technical Field

[0001] This invention relates to the field of chemical reaction equipment technology, and in particular to an apparatus and method for preparing a piperidine triazine derivative and an amine condensate. Background Technology

[0002] Traditional UV absorbers contain NH groups on their rings, exhibiting a certain degree of alkalinity. This limits their application in acidic resins, acidic compounding agents, and acidic environments. To broaden their application areas, research on low alkalinity has become a hot topic in HALS light stabilizers, especially N-alkoxy hindered amines. Products such as NOR116, Tinuvin123, TINUVIN152, NOR371, and LA-81 are already on the market. Among them, stabilizers with photostability and a certain degree of low alkalinity can be widely used in acidic systems of agricultural film coatings.

[0003] Currently, in the preparation of piperidine triazine derivatives and amine condensates, existing technologies typically employ batch reactors for material mixing and reaction. However, the feeding method and stirring mechanism have the following shortcomings: Traditional methods typically involve adding reactants to the main reaction vessel all at once or rapidly, lacking a smooth and controllable feeding process. This rapid feeding can easily lead to excessively high local concentrations, triggering side reactions or uneven mixing, thus affecting reaction efficiency and product purity. For example, in the preparation process, if TBHP (tert-butyl hydroperoxide) and piperidine triazine derivatives are not mixed sufficiently, localized peroxidation may trigger side reactions, reducing the yield. In addition, conventional stirring devices usually use fixed stirring paddles, which have a limited stirring range. Especially for high viscosity or heterogeneous systems (such as reaction liquids containing nano-catalysts), insufficient mixing will significantly prolong the reaction time. Finally, feeding and stirring are often operated independently, lacking a linkage mechanism. For example, the feeding position is fixed and cannot be dynamically adjusted during the stirring process, making it difficult for newly added materials (such as cyclohexane or TBHP) to disperse in a timely manner, thus slowing down the reaction process. In addition, the preheating function is separated from the stirring stage in traditional equipment, which can easily cause uneven heating of the materials, requiring additional time to balance the temperature.

[0015] The present invention provides an improved apparatus and method for preparing a piperidine triazine derivative and an amine condensate, which has the following improvements and advantages compared with the prior art: Firstly, when the cross strut retracts, the piston rod moves upward, discharging the material in the end cylinder through the one-way discharge valve and the three-way pipe. When the cross strut extends, the piston rod moves downward under the action of the extension shaft, drawing the material from the external feeding system into the end cylinder. This makes the material addition more uniform and gradual, and the addition position shifts with the extension and retraction of the cross strut, making it more dynamic and improving the mixing effect of the material. Secondly, when the main shaft cylinder of this invention moves horizontally, it promotes the vertical movement of the prism. Specifically, the main shaft cylinder is provided with a square groove, in which the prism can slide up and down.

[0019] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides an improved apparatus and method for preparing piperidine triazine derivatives and amine condensates. The technical solution of this invention is as follows: like Figures 1 to 11 As shown, this embodiment of the invention provides an apparatus for preparing a piperidine triazine derivative and an amine condensate, including a base 1, on which two pairs of support brackets 101 are fixed. A main tank 3 is rotatably mounted on each of the two pairs of support brackets 101, and a secondary tank 2 is fixedly mounted on each pair of support brackets 101. The support brackets 101 are used to support the main tank 3 and the secondary tank 2. The apparatus also includes: The mobile mixing assembly includes a pair of guide shafts 602, on which side arms 601 are slidably mounted. A connecting seat 6 is fixed to the opposite side of each side arm 601. A main shaft cylinder 7 is rotatably mounted on the connecting seat 6. A square groove is provided inside the main shaft cylinder 7, and a prism 701 is slidably mounted vertically within the square groove. A hoisting mechanism is provided at the top of the prism 701. The hoisting mechanism facilitates the vertical movement of the prism 701 when the main shaft cylinder 7 moves horizontally. Specifically, the main shaft cylinder 7 has a square groove within which the prism 701 can slide up and down. When the connecting seat 6 moves, the prism 701 adjusts its position vertically via the hoisting mechanism, achieving three-dimensional movement of the prism 701.

[0021] The follow-up feeding component enables dynamic material addition, ensuring that feeding and mixing are synchronized, thus improving mixing efficiency. The follow-up feeding component includes an H-shaped support rod 105 located on one side of the main tank 3, a pair of guide horizontal shafts 602 fixed between the top of the H-shaped support rod 105 and the base 1, and cross support rods 8 hinged between the two side arm rods 601 and the H-shaped support rod 105. Two guide connecting rods 603 are slidably installed on the two guide horizontal shafts 602, and a pair of end cylinders 801 are fixed on each guide connecting rod 603. A piston rod 804 is slidably installed inside each end cylinder 801, and an extension rod 803 is fixed to the bottom end of each piston rod 804. The extension rod 803 and the cross support rod 8 are connected by a transmission unit. Through the above structure, when the connecting seat 6 moves along the guide horizontal shaft 602, it can pull the cross support rod 8 to retract or expand, thereby moving the piston rod 804 and the end cylinder 801 while also moving the piston rod 804 in the vertical direction.

[0022] Furthermore, each cross strut 8 is rotatably connected via a movable shaft, and an extension shaft 805 is fixedly connected to one side of the movable shaft corresponding to the end cylinder 801 on each cross strut 8. Each extension rod 803 is rotatably connected to the extension shaft 805, and multiple paddles 806 are fixed on each extension rod 803. A heating wire is installed inside the lower half of the extension rod 803. The heating wire enables the extension rod 803 to have a heating function, thereby facilitating the heating and temperature rise of the material inside the main tank 3, ensuring that the reaction temperature reaches the preset value (such as 90℃), and creating conditions for subsequent reactions.

[0023] Furthermore, to prevent backflow and ensure a stable supply of materials to the external feeding system, a feeding pipe 808 is fixedly connected to the top of each end cylinder 801, and a one-way inlet valve 809 is fixedly installed on the feeding pipe 808. A three-way pipe 802 is fixedly connected to the side of the end cylinder 801 near the top, and a one-way outlet valve 807 is fixedly installed at one end of the three-way pipe 802. The feeding pipe 808 is connected to an external feeding system via a flexible hose. The external feeding system is used to supply 2,4-bis[N-butyl-[1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl]amino]-1,3,5-trimethylolpropionic acid. The condensate of aziridine and N,N-di(3-aminopropyl)ethylethylamine; with the above structure, when the cross strut 8 contracts, the piston rod 804 can move upward and discharge the material in the end cylinder 801 through the one-way discharge valve 807 and the three-way pipe 802; when the cross strut 8 extends, under the action of the extension shaft 805, the piston rod 804 can move downward and suck the material in the external feeding system into the end cylinder 801, so that the material addition is more uniform and gentle, and the addition position will be displaced with the extension and retraction of the cross strut 8, thus becoming more dynamic and improving the mixing effect of the material.

[0024] Furthermore, the hoisting mechanism includes a pair of guide rail brackets 102 fixed to the base 1, and the two guide rail brackets 102 are fixedly connected to a U-shaped rail groove 103 on opposite sides. The top of the prism 701 is rotatably connected to a lifting rod 104 via a bearing. Two rollers 106 are rotatably mounted on the lifting rod 104. The rollers 106 are in rolling contact with the inner wall of the U-shaped rail groove 103. It should be noted that the curvature of the U-shaped rail groove 103 is the same as the curvature of the bottom of the main tank 3. With the above structure, when the prism 701 moves with the connecting seat 6, the rollers 106 will move on the U-shaped rail groove 103, thereby adjusting the height of the prism 701 according to the U-shaped rail groove 103. This allows the stirring component to cover different height areas of the main tank 3, enhancing the stirring effect.

[0025] Furthermore, a drive motor 5 is fixedly installed on the side of the base 1 near the main tank 3, and the output shaft of the drive motor 5 is fixedly connected to an output main shaft 501. A drive wheel 503 is fixedly installed at the top of the output main shaft 501, and a transmission rod 504 is rotatably installed on the surface of the drive wheel 503. The other end of the transmission rod 504 is rotatably connected to the connecting seat 6 through a movable shaft. When the drive motor 5 is running, it can drive the drive wheel 503 to rotate through the output main shaft 501. In conjunction with the transmission rod 504, it can drive the connecting seat 6 to reciprocate along the guide horizontal axis 602. A drive gear 502 is fixedly installed on the output main shaft 501, and a driven gear ring 301 that meshes with the drive gear 502 is fixedly installed on the outer peripheral wall of the main tank 3. At the same time, when the output main shaft 501 drives the drive gear 502 to rotate, the main tank 3 can be driven to rotate through the transmission action of the driven gear ring 301, so as to improve the mixing effect of the material in the main tank 3.

[0026] Furthermore, a side support 107 is fixedly installed on the base 1, and a rack 108 is fixedly installed at the end of the side support 107. A driven gear 702 that meshes with the rack 108 is fixed at one end of the main shaft cylinder 7 near the top. When the main shaft cylinder 7 moves along the rack 108, the meshing action of the driven gear 702 and the rack 108 can drive the main shaft cylinder 7 to rotate. Moreover, when moving back and forth, the rotation direction of the main shaft cylinder 7 is opposite, which can further improve the mixing effect of the material in the main tank 3.

[0027] As a further embodiment of the present invention, a pair of side arm columns 9 are fixedly connected to the bottom end of the prism 701, and a plurality of symmetrically arranged stirring blocks 901 are fixedly connected to each side arm column 9. A plurality of perforated ring plates 902 are fixedly connected to both side arm columns 9. With the above structure, when the main shaft cylinder 7 rotates, it can synchronously drive the prism 701 to rotate. In conjunction with the side arm columns 9 and stirring blocks 901, and along with the main shaft cylinder 7, the stirring range of the side arm columns 9 can be effectively increased. At the same time, the prism 701 can move vertically under the action of the roller 106 and the U-shaped rail groove 103. In conjunction with the plurality of perforated ring plates 902, the stirring effect on the material can be effectively improved in the vertical direction. Specifically, the stirring blocks 901 are responsible for breaking up material clumps, while the perforated ring plates 902 promote the uniform dispersion and flow of the material through their perforated structure.

[0028] Furthermore, a pair of metering pumps 4 are fixedly installed on the base 1. The input ends of both metering pumps 4 are fixedly connected to the discharge pipes 402, and the output ends of both metering pumps 4 are fixedly connected to the output pipes 401. The ends of the two output pipes 401 are fixedly connected to an external reactor. Through the above structure, the materials in the main tank 3 and the auxiliary tank 2 can be fed into the external reactor by the metering pumps 4 to carry out the reaction. In this application, a self-made nano molybdenum oxide catalyst is synthesized and fully mixed in the external reactor under a back pressure of 0.5 MPa, which greatly improves the mixing efficiency, thereby effectively shortening the reaction time and increasing the yield.

[0029] Furthermore, to facilitate the control of the discharge of the main tank 3 and the auxiliary tank 2, an electric control valve is fixedly installed at one end of each of the two discharge pipes 402. The bottom end of the auxiliary tank 2 is fixedly connected to the discharge pipe 402 located at the bottom end. In order to avoid the main tank 3 rotating and causing motion interference with the discharge pipe 402 at the bottom, the bottom end of the main tank 3 is rotatably connected to the discharge pipe 402 located at the bottom end. At the same time, in order to improve the structural stability of the two discharge pipes 402, a reinforcing frame is fixed between the two discharge pipes 402 and the base 1.

[0030] The specific working method is as follows: Cyclohexane and nano-catalyst are added to the main tank 3. Piperidine triazine derivative and amine condensate are connected to the follow-up feeding component through an external feeding system. TBHP is stored separately in the auxiliary tank 2. The drive motor 5 is started, which drives the output main shaft 501 to rotate. The drive wheel 503 pushes the connecting seat 6 to move back and forth along the guide horizontal axis 602 through the transmission rod 504. When the connecting seat 6 moves, the side arm 601 drives the main shaft cylinder 7 to move horizontally. At the same time, the prism 701 slides up and down in the U-shaped rail groove 103 through the roller 106 to realize the three-dimensional movement of the stirring block 901 and the mesh ring plate 902. The cross support rod 8 extends and retracts with the movement of the connecting seat 6. The piston rod 804 is pulled by the extension shaft 805 to suck the material from the feeding pipe 808 into the end cylinder 801, and then into the main tank 3 through the three-way pipe 802. In addition, the heating wire preheats the material simultaneously. When the main shaft cylinder 7 moves, the driven gear 702 meshes with the rack rod 108, causing the main shaft cylinder 7 to rotate, which drives the stirring component to alternately rotate forward and backward, enhancing the mixing effect. The uniformly mixed material is pumped into the external reactor in proportion by the metering pump 4, and reacts continuously under high temperature and high pressure. After the reaction is completed, the product undergoes cooling, filtration, distillation and other steps to obtain a high-purity target compound. The catalyst and solvent can be recycled.

After grinding, filter the glass beads with sand cloth first, and then filter the filtrate through a 0.1-micron microporous membrane to obtain nano-sized wet catalyst. After drying the wet catalyst, the nano-catalyst is obtained. Step 2: Add the condensate of 2,4-bis[N-butyl-[1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl]amino]-1,3,5-triazine and N,N-bis(3-aminopropyl)ethyl ethylamine (24.9 wt%) to the external feeding system. Add cyclohexane (41.6 wt%) and nano-catalyst (0.2 wt%) to the main tank 3. Use the moving stirring component and the follow-up feeding component to mix the three evenly and preheat to 90°C. Step 3: Store 80% TBHP (33.3wt%) separately in auxiliary tank 2. Use metering pump 4 to feed the materials from main tank 3 and auxiliary tank 2 into the reactor, control the reaction temperature at 90℃ and the back pressure at 0.5 MPa, and continuously feed the reaction. Step 4: Take samples for testing. If the samples do not meet the standards, continue the reaction until they are qualified. Step 5: After the reaction is complete, cool to 60℃, filter to recover the catalyst, distill the filtrate under normal pressure to recover cyclohexane, and then desolvate in a high vacuum in a demelting kettle. The condensate of 2,4-bis[N-butyl-(1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl)amino]-1,3,5-triazine with N,N-bis(3-aminopropyl)ethylethylamine is obtained by granulation or pulverization, with a yield ≥95%.

10. A method for preparing a piperidine triazine derivative and amine condensate, wherein the method is applied to the apparatus for preparing the piperidine triazine derivative and amine condensate according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Add industrial-grade molybdenum trioxide (25wt%), deionized water (50wt%), and glass beads (25wt%) to a high-efficiency grinder mixing sampler and grind for more than 10 hours. Take samples to test the particle size until the laser particle size analyzer shows that D90 meets the requirements, where D90≤100nm. After grinding, filter the glass beads with sand cloth first, and then filter the filtrate through a 0.1-micron microporous membrane to obtain nano-sized wet catalyst. After drying the wet catalyst, the nano-catalyst is obtained. Step 2: Add the condensate of 2,4-bis[N-butyl-[1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl]amino]-1,3,5-triazine and N,N-bis(3-aminopropyl)ethyl ethylamine (24.9 wt%) to the external feeding system, and add cyclohexane (41.6 wt%) and nano-catalyst (0.2 wt%) to the main tank (3). Use the moving stirring component and the follow-up feeding component to mix the three evenly, and preheat to 90°C; Step 3: Store 80% TBHP (33.3wt%) separately in auxiliary tank (2), and use metering pump (4) to feed the materials from main tank (3) and auxiliary tank (2) into the reactor, control the reaction temperature at 90℃ and the back pressure at 0.5 MPa, and continuously feed the reaction. Step 4: Take samples for testing. If the samples do not meet the standards, continue the reaction until they are qualified. Step 5: After the reaction is complete, cool to 60℃, filter to recover the catalyst, distill the filtrate under normal pressure to recover cyclohexane, then desolvate in a high vacuum in a demelting kettle, and granulate or pulverize to obtain the condensate of 2,4-bis[N-butyl-(1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl)amino]-1,3,5-triazine and N,N-bis(3-aminopropyl)ethylethylamine, with a yield ≥95%.
