Abstract
The invention is a process for epoxidizing an olefin with hydrogen and oxygen in a solvent comprising acetonitrile in the presence of an quinone-acid salt and a catalyst comprising a titanium zeolite and a noble metal. The process results in higher productivity and improved selectivity to propylene oxide from hydrogen and oxygen, as compared to processes that use only a quinone.
