(57)Abstract
A process and catalyst for the direct oxidation of an olefin having three or more carbon atoms, such as propylene, by
oxygen to an olefin oxide, such as propylene oxide. The process involves contacting the olefin under reaction
conditions with oxygen in the presence of hydrogen and a catalyst. The catalyst comprises gold, at least one promoter
metal, and a titanium-containing support. Preferably, the promoter metal is selected from Group 1, Group 2, the
lanthanide rare earths and actinide metals of the Periodic Table, and combinations thereof. Suitable supports include
titanium dioxide, titanosilicates, promoter metal titanates, titanium dispersed on silica, and promoter metal silicates.
