| 摘 要： | 采用胶束催化，在油水两相体系中，进行了2-氯乙基苯的氯甲基化反应．通过比较阴离子、阳离子和非离子三种类型表面活性剂的催化效果，探索了2-氯乙基苯氯甲基化反应的机理及胶束催化的作用机理．研究结果表明，胶束催化是实现2-氯乙基苯氯甲基化的有效途径，且阳离子表面活性剂胶束催化的效果最为显著，阳离子表面活性剂的疏水链越长，其催化性能越好；在水相中加入无机电解质，能显著促进胶束催化作用．

| Abstract: | In this work, the chloromethylation reaction of 2-chloroethylbenzene was performed successfully by micellar catalysis in biphasic oil/water system. The effects of anionic, cationic and non-ionic surfactants on the reaction were compared. The mechanism of chloromethylation reaction and the mechanism of micellar catalysis were investigated. The results show that the micellar catalysis is an effective way to realize the chloromethylation of 2-chloroethylbenzene, and the cationic surfactant showed the most effe... |
