摘要/Abstract

摘要： 采用环氧氯丙烷和三甲胺制备季铵盐型活性醚化剂为环氧氯丙基三甲基氯化铵时，由于三甲胺为气态，其合成工艺较难控制，为此，探讨用液态三乙胺替代气态三甲胺合成季铵盐型阳离子醚化剂环氧氯丙基三乙基氯化铵（GTA）的方法。通过分析合成工艺参数对GTA产率的影响，获得了最佳合成工艺。并对产物GTA的元素含量、环氧值、熔点、水溶性进行了测试。GTA产率94.53％，环氧值90.36％，熔点在138～140℃。认为产品的性能优良，液态三乙胺的使用使反应过程易于操作控制，符合工业化批量生产的要求。

Abstract: When preparing quaternary ammonium salt type active etherifying agent- epoxychloropropyl triethylammonium chloride with epichlorohydrin and trimethylamine, its synthesizing process is difficult to control, for trimethylamine is a kind of gas. For this reason, this paper investigates synthesizing quaternary ammonium salt type cationic etherifying agent- epoxychloropropyl triethylammonium chloride with liquid triethylamine substituting for gaseous trimethylamine. The effect of synthesizing conditions on the product yield is analyzed and the optimal process conditions are determined. The element content, epoxy value, melting point, and water solubility of the product are tested, and it is found that the product yield is up to 94.53%, epoxy value is 90.36％, and melting point is 138～140℃. It is considered that the quality of the product is good.The use of liquid triethylamine makes the reaction process easy to control, thus meeting the requirement commercial product by lot.
