Epoxidation of allyl acetate with tert-butyl hydroperoxide catalyzed by MoO3/TiO2 Original Research Article

Selective epoxidation of allyl acetate with tert-butyl hydroperoxide (TBHP) over the groups IV–VI metal oxides supported on SiO2, Al2O3 and TiO2 has been studied. The epoxidation required higher temperatures than those of α-olefins and cycloolefins did. The poor epoxidation selectivity was attributed to concurrently occurring reactions of epoxides produced during epoxidation. The highest yield of epoxide was achieved over MoO3/TiO2 with an adequate MoO3 loading which was determined so that the surfaces of TiO2 were two-dimensionally and fully covered with MoO3.
