【摘要】 用柠檬酸、十二烷基二甲基叔胺与环氧氯丙烷反应合成了柠檬酸三酯三烷基季铵盐阳离子表面活性剂。实验结果表明,在异丙醇溶剂中,反应体系在80℃,反应时间12h,产物的收率为91.5%。用红外光谱、元素分析、高效液相色谱对其结构进行了表征,通过测定其临界胶束浓度、Krafft点及泡沫性能,对产物表面活性进行了分析。更多还原

【Abstract】 A new type of citric triesters of tridodecyl triammonium(CTTTA)cationic surfactant was synthesized by citric acid,epoxy chloropropane and dodecyl dimethyl amine.In the solvent of 2-propanol,the yield of CTTTA is 91.5% while the ratio of three reactants is l:l:l,the reaction temperature is 80℃ and the reaction time is 12 hr.The structure was characterized by IR spectrum,elementary analysis,and HPLC.By measuring its cmc,krafft point and foam properties,Is surface activities were analysised.更多还原
