摘 要:为寻找更好的相转移催化剂,合成了含有乙氧基的季铵盐,并对其催化剂性能进行了初步测试。结果证明,该催化剂的合成反应属二级反应,其速度常数k值随EO数的不同和有无溶剂存在,均在0.045~0.095之间。通过二氯卡宾对己烯加成反应中的应用,证明该催化剂的性能优于普通季铵化合物催化剂。Abstract: In order to seek more efficient catalyst for phase tranfer catalysis, a quaternary ammonium compound contained (EO)n were synthesized and catalytic activity of this catalyst were determined.these results show that the synthesis was second order reaction, the rate constant was between 0.045-0.095mol/hr.1 depending the EO numbers attached on the molecule of quaternary ammonium salt, as well as with or without DMF solvents in the system.Sequentially, it was demonstrated that the catalytic activity was superior to common quaternary ammonium salts.
