Using tert-butyl hydroperoxide(TBHP)as the oxidant and selfmade phosphorus molybdenum compound as the catalyst,bicycloalkenyl ester can be epoxidized to diepoxide. The structure of the catalyst was characterized by XRD and SEM. The results showed that phosphorus molybdenum composite catalysts had good catalytic activity on the epoxidation of bicycloalkenyl ester. In the absence of a solvent ,t-butyl hydrogen peroxide as the oxidant,Mo complex+HPW as the catalyst,the reaction time controlled to 2.5 h at 105℃,the conversion of bicycloalkenyl ester was 98.6%and the selectivity of diepoxide was 90.1%.
