【摘要】 以聚氧乙烯脂肪醇和环氧氯丙烷在相转移催化条件下反应，高收率得到聚氧乙烯脂肪醇缩水甘油醚，以此为原料和三甲胺盐酸盐反应定量得到Ｎ－［３－单（双）氧乙烯长链烷氧－２－羟］丙基－Ｎ，Ｎ，Ｎ－三甲基氯化铵，通过元素分析，红外光谱和核磁共振氢谱对其结构进行了鉴定。更多还原

【Abstract】 N [3 Alkylmono(di) oxyethylene oxy 2 hydroxy] propyl N,N,N trimethylammonium chloride,were synthesized from trimethylammonium chloride and polyoxyethylene fatty alcohol glycidylethers which were prepared at high yield by phase transfer catalyzed synthesis of polyoxyethylene fatty alcohol and epichlorohydrin.Their structures were confirmed by IR, 1HNMR Spectra and elemental analysis.更多还原
