【摘要】 脂肪酸和表江醇反应得到相应的还代甘油欧，以此为原料分别和二甲胺和氯乙酸钠进行胺化和季铵化，最后得到N-（3-十二烷氧－2－羟）丙基－N，N－二甲基甜菜碱，本文讨论了合成方法和条件，并探讨了其表面活性。更多还原

【Abstract】 Preparing N- (3- dodecyl - oxy - 2- hydroxy ) propyl-N, N-dimethyl betaine involves reaction of fatty alcohol with epichlorohydrin to forme corresponding chloroglyceryl ether which can be aminated and quaterni zed in two stages,by reaction of a dimethyl amine and sodyum chloroacetate- The synthetic method and condition were studied and its surfactancy ware analysed.更多还原
