摘　　要：在20℃条件下,运用电导测定方法及非线性动力学模型进行数据处理,得到了在不同浓度十六烷基三甲基溴化胺(CTAB)胶束水溶液中正脂肪酸乙酯(甲酸乙酯,乙酸乙酯,丙酸乙酯,丁酸乙酯及正戊酸乙酯)碱性水解反应的速率常数.依据离子交换模型(PIE)理论讨论了在第一和第二临界胶束浓度(CMC)时,CTAB对正脂肪酸乙酯碱性水解反应速率的影响及规律性.The catalysis of CTAB and its regularity was investigated by conductance and the model of non-linear curves fitting. There are the same varying trends and the regularities at the first Critical Micelle Concentration (1st CMC) and the second Critical Micelle Concentration (2nd CMC) of CTAB aqueous micelle solution. The Pseudo-phase Ion-Exchange (PIE) models are applied to the study of the micelle catalysis and its mechanisms. The results of this research will be of great theoretical and practical significance in the study of micelle catalysis and its practical (applications.)
