Abstract
A process for producing an epoxide such as a cycloaliphatic diepoxide by the reaction of an olefin such as a cycloaliphatic diene with hydrogen peroxide (H2O2) as an oxidant in the presence of a catalytic system under pH control for example at a pH of less than about 5. The present invention is advantageously used for the epoxidation of olefinic compounds such as olefins and aliphatic or aromatic dienes.
