摘要:
在大孔聚苯乙烯-二乙烯苯交联树脂(PS)上接枝金属卤化物做为催化剂,以二氧化碳和环氧环己烷为原料及季铵盐为助催化剂,在无溶剂条件下合成了碳酸环己烯酯,考察了催化剂用量和反应压力、温度、反应时间、搅拌速度对反应的影响.结果显示:在以季铵盐为助催化剂、温度为120℃、初始压力为4.5 MPa、转速为300 r/min的条件下反应6h,碳酸环己烯酯的产率达96％以上,催化剂使用5次产物产率没有明显变化,得出PS接枝金属卤化物催化剂具有良好的催化活性.
Abstract:
Using macroporous polystyrene divinylbenzene cross-linked resin( PS ) grafted metal halide as catalyst and using CO, with cyclohexene oxide as materials have successfully synthesized cyclohexene carbonates inthe condition of quaternary ammonium salt and solvent-free. The factors infuencing the reaction were studied,such as dose of catalysts, reaction pressure, reaction temperalure, reaction time as well as revolving speed.The results show that the yield of cyclohexene carbonates could reached 96% under the following conditions,using quaternary ammonium salt as co-catalysts, 120 ℃, initial pressure of 4.5 MPa, revolving speed of 300r/min, 6 h. The aclivity of the catalyst had not decreased obviously after being used for $ times, so PS graftedmetal halide has good catalytie activity.
