摘　　要：研究了异丙醇作为溶剂时，TS-1催化丙烯H2O2环氧化反应过程主副反应动力学，分析了丙烯压力、温度等因素对反应的影响，发现当温度低于40oC、丙烯压力为0.3 MPa时，环氧丙烷的收率达到75%，可以采用异丙醇法制H2O2与丙烯环氧化集成.：The epoxidation of propylene with H2O2 in isopropanol under mild conditions over TS-1 molecular sieve was studied, the primary and side reaction kinetics was discussed, and the effects of temperature, pressure and other factors on reactions were analyzed. It was found that when pressure of propylene was 0.3 MPa and temperature below 40oC, the yield of propylene oxide was up to 75%, and the integration of propylene epoxidation with manufacture of H2O2 via isopropanol was possible.
