Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical reaction equipment, in particular to a preparation device and method of piperidine triazine derivative and amine condensate. BACKGROUND

[0002] Traditional ultraviolet absorbers have N-H groups on the ring, which have certain alkalinity, limiting their application in acidic resins, acidic complexing agents and acidic environments. In order to expand the application field, low alkalinity research has become a research hotspot for HALS light stabilizers. In particular, N-alkoxy hindered amines, such as NOR116, Tinuvin123, TINUVIN152, NOR371, LA-81, have been put on the market. Among them, as a light stabilizer with light stabilizing performance and certain low alkalinity on the market, it can be widely used in acid system of agricultural film coating.

[0003] At present, in the preparation process of piperidine triazine derivative and amine condensate, the existing technology usually adopts batch reaction kettle for material mixing and reaction, and the feeding mode and stirring mechanism have the following disadvantages:

[0004] Traditional methods usually add reaction materials to the main tank at one time or quickly, lacking a smooth and controllable feeding process. Such rapid feeding can easily lead to local high concentration, causing side reactions or uneven mixing, affecting reaction efficiency and product purity. For example, in the preparation of, if TBHP (tert-butyl hydroperoxide) is not fully mixed with piperidine triazine derivative, side reactions may be caused by local peroxidation, reducing the yield;

[0005] In addition, the conventional stirring device usually adopts fixed stirring paddle, and the stirring range is limited. Especially for high viscosity or heterogeneous system (such as reaction liquid containing nano catalyst), insufficient mixing will significantly prolong the reaction time;

[0006] Finally, feeding and stirring are usually operated independently, lacking linkage mechanism. For example, the feeding position is fixed and cannot be dynamically adjusted with the stirring process, making it difficult to disperse the newly added materials (such as cyclohexane or TBHP) in time, slowing down the reaction process. In addition, the preheating function and stirring link in the traditional device are separated, which can easily cause uneven heating of the materials and requires additional time to balance the temperature.

8. A method for producing a piperidine triazine derivative and amine condensate, using the apparatus for producing a piperidine triazine derivative and amine condensate according to any one of claims 1 to 7, characterized by: The steps include the following steps: Step one, put the industrial grade molybdenum trioxide with a mass fraction of 25%, deionized water with a mass fraction of 50% and glass beads with a mass fraction of 25% into a high-efficiency grinding machine mixing sampler, stir and grind for more than 10 hours, take sample to detect particle size, until the laser particle size analyzer shows that D90 reaches the requirement, wherein D90≤100nm, after grinding, first filter the glass beads with sandpaper, then filter the filtrate through a 0.1 micron microporous filter membrane to obtain a nanoscale wet catalyst, and after the wet catalyst is dried, a nanocatalyst is obtained; Step two, add 2,4-di[N-butyl-[1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl] amino]-1,3,5-triazine with a mass fraction of 24.9% and N,N-di(3-aminopropyl)ethylamine condensate to an external feeding system, add cyclohexane with a mass fraction of 41.6% and nanocatalyst with a mass fraction of 0.2% to the main tank (3), mix the three uniformly by using a moving stirring assembly and a follow-up feeding assembly, and preheat to 90℃; Step three, store 80% TBHP with a mass fraction of 33.3% in the auxiliary tank (2) alone, pass the materials in the main tank (3) and the auxiliary tank (2) into the reactor by using the metering pump (4), control the reaction temperature to be 90℃ and the back pressure to be 0.5MPa, and continuously feed to react; Step four, sampling detection, if not up to standard, continue the reaction until qualified; Step five, after the reaction is completed, the temperature is decreased to 60°C, the catalyst is recovered by filtration, the filtrate is recovered by distillation under normal pressure, and then is subjected to high-vacuum desolventization in a desolventizing kettle, and is formed into a shape by a granulator or a pulverizer to obtain the 2,4-di[N-butyl-(1-cyclohexyloxy-2,2,6,6-tetramethylpiperidin-4-yl)amino]-1,3,5-triazine and N,N-di(3-aminopropyl)ethylamine condensate, and the yield is ≥95%.
