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 polymer-encapsulated noble metal catalyst. The noble metal catalyst comprises a noble metal and an ion-exchange resin. The process using the polymer-encapsulated noble metal catalyst gives higher epoxide productivity than a process that uses a noble metal catalyst which is not encapsulated by a polymer.
