【摘要】 脂肪醇和环氧氯丙烷在相转移条件下反应得到长链烷基缩水甘油醚，以此为原料和三甲胺氢溴酸盐反应得到溴化N－（3－长链烷氧－2－羟）丙基－N，N，N－三甲基铵。其结构通过红外光谱，核磁共振氢谱及元素分析结果得以证实。本文还测定所合成产品的表面张力和临界胶束浓度等。更多还原

【Abstract】 N-(3-long chain alkyloxy- 2 - hydroxy ) propyl-N, N, N-trimethyl ammonium bromide were synthesized from the reaction of trimethyl ammonium bromide and long chain alkyl glycidyl ether which were prepared from fatty alcohol and epichlorohydrim under a condition of phase transfer catalyst in a yield of 97%.Their structures were confirmed by IR,HNMR and elemental analyses. Surface tension and critical micelle concentration of the products were also determined in this paper.更多还原
