- 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.
