摘　　要：研究了具有非离子和阳离子双重特性的表面活性剂──双（月桂酸）三乙醇胺酯在稀盐酸溶液中未成囊泡的性质．发现只有当溶液pH值小于4．2时，囊泡才能形成，而在溶液pH值2~3范围内，囊泡稳定性和“耐盐”能力最佳．这些特性被归之于此化合物酸性水解作用的结果．The properties of the vesicles from triethanolamine dilaurate (ZRNC_2) whicll Possessesthe characteristics of both nonionic and ionic surfactants in the diluted solution of hydrochloricacid have been studied. It, is shown that the vesicles are not formed until the PH value of thesolutioll is lower than 4.2, the vesicle the aqueous solution with and without NaCl has the best stability within pH=2~3 range These phenomena are due to the partial transformation of2RNC2 into chloride salt of triethanolamine dilaurate'.
