摘　　要：以环己烯二甲酸二甲酯、N,N-二甲基-1,3-丙二胺、溴代十二烷为原料,合成了一种新型阳离子双子表面活性剂KB-12。以KB-12作为相转移催化剂,研究其对乙酸钠和氯乙酸乙酯反应的催化性能。结果表明,在30℃下,反应速率常数K与KB-12浓度c符合线性方程K=0.122＋5.735c;当KB-12的浓度为0.012 mol/L时,反应表观活化能降低了11.136k J/mol。对比了不同阳离子表面活性剂的催化效果,催化活性顺序为KB-12〉十六烷基三甲基溴化铵〉四丁基溴化铵〉十二烷基三甲基溴化铵〉苄基三甲基氯化铵。A novel cationic Gemini surfactant （ KB- 12） was synthesized with dimethyl cis- 1,2,3,6-tetrahydrophthalate, N, N-dim- ethyl-1,3-propyldiamine,and 1-bromododecane.Using KB-12 as phase transfer catalyst,the reaction of the catalytic properties of sodium acetate anhydrous and ethyl chloroacetate was investigated.The result showed that at 30 ℃ ,the reaction rate constant K was linearly related to the catalyst concentration of KB-12, the linear equation was K= 0. 122＋5. 735c.When the KB-12 was 0. 012 mol/L,the apparent activation energy can be reduced by 11. 136 kJ/mol.The catalytic effect of different cationic surfactants was compared,the order of catalytic effects was KB-12〉N,N,N-trimethylhexadecan-1-aminium bromide 〉tetrabutyl ammonium bromide〉dodecyltrimethylammonium bromide〉benzyhrimethylammonium chloride.
