摘　　要：以邻苯二甲酸二甲酯及N,N-二甲基乙醇胺为原料,甲醇钠的甲醇溶液为催化剂,经酯交换反应,合成中间体N,N-二甲基氨基乙基邻苯甲酸酯（I）,收率24.90%。I与1-溴代正辛烷进行季铵化反应,生成含酯基不对称阳离子表面活性剂（II）,收率51.61%。通过对季铵化反应单因素试验条件的考察,确定了较佳的工艺合成条件。中间体和产物的结构由~1H-NMR、IR进行表征。The intermediate N,N-dimethylaminoethyl benzoate（I） was synthesized from dimethyl phthalate ester,N, N-dimethyl ethanolamine catalyzed by sodium methoxide-methanol solution by transesterification. The yield of I is 24.90%. Ester containing asymmetric cationic surfactant（ll） was synthesized with the N,N-dimethylaminoethyl phthalate ester and 1-bromooctane by quaternization. The yield of II is 51.61%. The optimum conditions were investigated by single factor experimental. The structures of intermediate and product are verified by 1H-NMR and IR.
