摘　　要：用碘化钾催化CO2与氧化苯乙烯(SO)合成苯乙烯环状碳酸酯,分别从溶剂、催化剂用量、温度、CO2压力和反应时间进行探讨,得出了最佳条件.结果表明:以无水乙醇为溶剂,催化剂用量r(KI∶SO)=1∶250,在170℃,CO2压力5 MPa,反应时间5 h,苯乙烯环状碳酸酯的产率和选择性均达到100%.Potassium iodide was used to catalyze the coupling reaction of carbon dioxide and styrene oxide for the production of styrene carbonate. The effects of solvent,catalyst amounts,temperature,CO2 pressure and reaction time were assessed to obtain the optimal condition. The results showed that both the yield and selectivity of styrene carbonate could reach to 100%,using anhydrous ethanol as solvent,with the mole ratio of potassium iodide and styrene oxide of 1 ∶ 250,under 170℃ and 5 MPa of CO2 pressure for 5 h.
