Title: Process for the direct oxidation of olefins to olefin oxides

Abstract: A process and catalyst for the direct oxidation of an olefin having threeor more carbon atoms, such as propylene, by oxygen to the correspondingolefin oxide, such as propylene oxide. The process involves contacting theolefin with oxygen under reaction conditions in the presence of hydrogenand in the presence of a catalyst. The catalyst comprises gold on atitanosilicate, preferably a microporous or mesoporous titanosilicate,such as, TS-1, TS-2, Ti-beta, Ti-ZSM-48, or Ti-MCM-41. Selectivity to theolefin oxide is high at good conversions of the olefin. The catalyst isreadily regenerated, and the time between catalyst regenerations is long.
