Preparation of hyperactive etherifying agent of glycidyltriethylammonium chloride

[Purpose] In order to reducing the toxicity of general cationic surfactants, biodegradable ester cationic surfactants have been developed as novel kinds of environmental products in the world. [Method] Hyperactive etherifying agent of glycidyltriethyl ammonium chloride is very important intermediate product to synthesis biodegradable ester cationic surfactants. In this paper, a kind of hyperactive etherifying agent of glycidyltriethylammonium chloride was synthesized by traditional method with epichlorohydrin and trimethylamine as raw materials. [Results] During the synthesis, the best reaction conditions have been obtained, that the reaction temperature is 25 oC, the reaction time is 3 h, the reaction solvent is acetone, and the best mol ratio of epichlorohydrin to timethylamine is 3:1. [Conclusions] In addition, the chemical structure of the product has been confirmed by FT-IR, it is conformed with glycidyltriethylammonium chloride completely.
