Abstract
The invention is a process for epoxidizing an olefin with hydrogen and oxygen in a solvent comprising tertiary butyl alcohol or acetonitrile in the presence of an amide modifier and a catalyst comprising titanium-MWW zeolite and a noble metal. The process produces less ring-opened products such as glycols and glycol ethers when performed in the presence of the amide, while maintaining low alkane byproduct formed by the hydrogenation of olefin.
