Abstract

A process for the catalytic epoxidation of olefins by means of hydrogen peroxide and a titanium zeolite catalyst, wherein the epoxidation reaction is carried out in a reaction system through which the reaction mixture flows continuously and the regeneration of deactivated catalyst is carried out by means of hydrogen peroxide in the presence of the olefin while continuing the epoxidation reaction.
