Synthesis method

1. Prepared by the reaction of tetradecyldimethyltertiary amine and benzyl chloride. Use tetradecyldimethylamine as raw material, react with benzyl chloride, and perform quaternization
This product can be prepared by the reaction, but due to domestic The raw material of tetradecanol often contains a certain amount of dodecanol, so the tetradecyldimethyltertiary amine produced by the new catalytic ammoniation process of tetradecyl alcohol and dimethylamine also often contains a certain amount of dodecanol. Alkyl dimethyl tertiary amine, so the product often contains a certain amount of dodecyl dimethyl benzyl ammonium chloride. Take 241 parts of tetradecyldimethyl tertiary amine, add 126.5 parts of benzyl chloride at a temperature not exceeding 100-110°C, and heat at 120°C for 2 hours to obtain a light yellow viscous liquid, which is cooled into a solid. The yield is 90%. above.
The reaction formula is as follows:


1. Commonly used cationic surfactants can improve the performance of analytical reagents, such as increasing the sensitivity of glyoxal bis-(2-hydroxyaniline) when measuring calcium and increasing the stability of chromium azure S when measuring aluminum.

2.This product is the main component of JN- bactericidal algaecide. Good compatibility with non-ionic, zwitterionic and other cationic active substances. Good thermal stability.

3.It is commonly used as a bactericidal algaecide, slime stripper and system cleaning agent in industrial circulating water treatment.
