水法合成阳离子醚化剂3-氯-2-羟丙基三甲基氯化铵的研究
The Study on Synthesis of Cationic Etherification Agent “CHPTMA” under Aqueous Process.
【摘要】 采用工业级三甲胺气体、36%的盐酸、环氧氯丙烷,常温水法合成3 氯 2 羟丙基三甲基氯化铵。结合其反应原理,研究了反应温度、环氧氯丙烷的滴加时间、总反应时间、反应液pH值、催化剂、环氧氯丙烷与三甲胺盐酸盐的用量比和反应介质对产物收率的影响。
【Abstract】 The synthesis of 3 chloro 2 hydroxypropyl trimethylammonium chloride (CHPTMA) under aqueous process at room temperature was discussed. Trimethylamine hydrochloride (TMAHC) was firstly prepared from trimethylamine (Industrial grade) and hydrochloric acid (w=36%), then epichlorohydrin (EPIC) was dropped in it. The effects of the reaction temperature, drop time of EPIC, total reaction time, pH, catalyst, reaction medium, and molar ratio of EPIC and TMAHC on yield of CHPTMA were studied.
