摘　　要：采用二氧化碳插入法,以季铵盐为催化剂,在高温高压下合成环碳酸酯。讨论了温度、压力、催化剂对转化率的影响,并通过红外和核磁谱图表征了环碳酸酯的结构。结果表明:以乙二醇二缩水甘油醚为原料,四丁基溴化铵为催化剂时,最佳工艺条件为温度100℃,CO2压力2.0 MPa,催化剂的质量为环氧化物的3%。Cyclic carbonate is synthesized from glycol diglycidyl ether and carbon dioxide under high temperature and high pressure with quaternary-N as the catalyst. The effects of tempera- ture, pressure and catalyst on the reaction conversion rate are discussed. The structure of cyclic carbonate is characterized by infrared and nuclear magnetic resonance spectra （1 H-NMR） which demonstrate the generation of cyclic carbonate group. The results show that the optimal process is： temperature 100 ℃, CO2 pressure 2.0 MPa and mass ratio of catalyst to diglycidygl ether 3 %when glycol diglycidyl ether is the initiator with tetrabutyl ammonium bromide as catalyst.
