| Abstract: | A divacant lacunary heteropoly compound （C_4H_9）_4N]_4γ-SiW_（10）O_（34）（H_2O）_2] is prepared and studied in the epoxidation of cyclohexene. The influences of reaction temperature, reaction time, material ratios and the amount of catalyst on the reaction are studied and the optimal reaction conditions are obtained. It is found that the catalyst can be recycled by distillation under reduced pressure after reaction. |
