Problems solved by technology

[0003] (1) Since industrial hydrochloric acid contains about 70% of water, the resulting triallyl ammonium chloride product contains a large amount of water. Although some manufacturers remove part of the water by vacuum heating and distillation, according to the principle of physical and chemical entropy increase , an isolated system cannot develop towards a low-entropy state, that is, it will not become orderly, and it is very difficult to separate two mixed substances into two pure substances
Both the laboratory and industrial production have proved that the distillation of 60% aqueous solution of triallyl ammonium chloride, along with the increase of the concentration of triallyl ammonium chloride, makes the distillation difficult, the concentration rate gradually decreases, and consumes a lot of energy. General industrial distillation can only obtain products with a concentration of about 70%, and it is very difficult to make 90% products by this method
[0004] (2) direct titration of triallylamine with hydrochloric acid, due to violent acid-base neutralization reaction, exothermic heat is big, and high temperature easily makes triallyl ammonium chloride produce amino discoloration reaction, and product discoloration is more serious, thereby makes obtained The product has quality problems
[0005] (3) The carbon-carbon double bond is in the aqueous solution state, and the carbon-carbon double bond will open under the condition of high heat or an initiator to undergo a polymerization reaction, and the reaction of titrating triallylamine with hydrochloric acid is carried out in an aqueous solution, and the heat released by the reaction is easy to initiate Micropolymerization of triallyl ammonium chloride monomer affects product quality
[0006] (4) Directly passing hydrogen chloride gas into triallylamine will cause a violent reaction, the heat cannot be transferred out in time, and improper control will cause explosion hazards

Abstract

The invention provides high-purity triallyl ammonium chloride and a preparation method thereof. According to the method, triallylamine is dissolved in a non-polar organic solvent, hydrogen chloride gas is slowly introduced into an organic liquor for a reaction under the cooling condition, a product obtained after the reaction is subjected to liquid-solid separation, a solvent on the surface of a solid is dried, and the high-purity triallyl ammonium chloride product is obtained. The triallylamine is dissolved in the nonpolar organic solvent, so that the reaction concentration of triallylamine is controllable, the nonpolar organic solvent can better transfer heat, and the system temperature is kept stable. Hydrogen chloride gas is introduced into a reactor, hydrogen chloride gas and triallylamine are subjected to a reaction on the bubble surface by use of the principle of surface reactology, the problem of violent reaction due to direct addition of hydrochloric acid or hydrogen chloridegas to triallylamine is solved, and the safety is improved.
