摘　　要：分别以合成的4种离子液体为反应溶剂,CH3ReO3为催化剂,UHP为氧化剂,对环己烯进行环氧化催化.实验结果表明,在4种离子液体为溶剂的体系中,其中[emi]SE离子液体为反应溶剂的催化效果最好.在MTO/[emi]SE催化环氧化环己烯的体系中,最优催化反应条件为:n(催化剂):n(底物):n(氧化剂)=2:100:200,离子液体1.2 ml.The catalytic system was established by using MTO as catalyst,UHP as oxidant,and four kinds of ionic liquids as reaction solvents,and the properties of catalytic epoxidation for cyclohexene were investigated. The results indicated that it is an effective system for epoxidetion of cyclohexene with better activities at the room temperature. The epoxidation is the best when using [emi]SE ionic liquid as solvent,the best reaction conditions of olefins at room temperature are by orthogonal experiment：2 mmol cyclohexene as substrate, the catalyst ： substrate： oxidant 2 ： 100 ： 200, ionic liquid 1.2 ml.
