英文摘要: The effects of solvents and quaternary ammonium ions in Q(3)[PO4(WO3)(4)] (Q= pi-C5H5NC16H33) on epoxidation of cyclohexene with 30% H2O2 were investigated. In the epoxidation, chloroform and t-butanol gave the best results. On the other hand, only the quaternary ammonium cations with suitable number of carbon atoms could form a reaction-controlled phase-transfer catalyst. In proper solvents, the initially insoluble catalyst could form soluble active species under the effect of H2O2 to lead to homogeneous catalytic epoxidation of olefins. When H2O2 was used up, the catalyst returned to its original structure and precipitated from the reaction medium.
