Abstract
The invention is a liquid-phase process for epoxidizing an olefin with hydrogen and oxygen in the presence of a supported catalyst comprising palladium on niobium-containing support. The process exhibits good productivity and selectivity for olefin epoxidation with hydrogen, and oxygen. This is particularly surprising because typical palladium-containing epoxidation catalysts require the presence of a titanium zeolite.
Claims17
A process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in a solvent in the presence of a supported catalyst comprising palladium and a support, wherein the support is an inorganic oxide containing niobium.
A process for producing propylene oxide comprising reacting propylene, hydrogen and oxygen in water in the presence of a supported catalyst comprising palladium and Nb2O5.
