Abstract
A process for the direct oxidation of an olefin by oxygen to the corresponding olefin oxide in the presence of a reducing agent and a catalyst. The catalyst comprises a metal component, such as a transition metal oxide, dispersed on a metal ion-exchanged metallosilicates, such as a Group 1 or Group 2 ion-exchanged porous aluminosilicate. Selectivity to the olefin oxide is high and the catalyst is readily regenerated.
