Abstract
Titanovanadosilicalites have been found to be very selective, active catalysts in the epoxidation of olefins by peroxides. Dilute hydrogen peroxide suffices to afford high yields of the epoxide. Vanadium incorporation at levels of Si:V in the range 100-2500 effectively changes the characteristics of the titanosilicalite into which it is incorporated to give near quantitative conversion of propylene at selectivities greater than 90%.
