ABSTRACT:
A process is disclosed for the epoxidation of an olefin with hydrogen and oxygen in the presence of an oxidation catalyst comprising a transition metal zeolite, and a noble metal catalyst comprising a noble metal and an ion-exchange resin. The process is highly productive and selective in making epoxides. A noble metal catalyst comprising a cation-exchanged resin further improves the productivity and/or the selectivity of the process.
