Abstract:A cationic etherifying agent(CHPTA)was synthesized by the reaction of epichlorohydrin with trimethylamine hydrochloride in aqueous phase. The effects of reaction time,temperature and ratio of reactants on the crystallization process of the product have been explored. The results indicated that the crystallization point of the product could be decreased to below -18℃ when epichlorohydrin was dropwised at lower temperature(10±1℃),reaction time was 2 hours below 25℃and 3 h below 35℃,the molar ratio of trN.S to EPI was 0.95 to 1.00. |
Key words:cationic etherifying agent;crystalline point;solid content |
