摘　　要：本文首先在相转移催化条件下合成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，并测定了产物的临界胶束浓度（ＣＭＣ）。N- 3-Alkylmono(di)oxyethylene oxy-2-hydroxy propyl-N,N,N-trimethylammonium chloride were synthesized from trimethylammonium chloride and poloxyethylene fatty alcohol glycidyl ethers. Polyoxyethylene fatty alcohol glycidyl ethers were prepared at high yield from polyoxyethylene fatty alcohol and epichlorohydrin by phase transfer catalyzed synthesis. Their structure were confirmed by IR,'HNMR spectra and elemental analysis. Their properties such as surface tension and critical micelle concentration were also determined.
