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.
Claims24
A process for the catalytic epoxidation reaction of an olefin comprising reacting a reaction an olefin with hydrogen peroxide in the presence of a titanium zeolite catalyst as a reaction mixture, wherein the reacting for the epoxidation is carried out in a reaction system through which the reaction mixture flows continuously and regenerating deactivated catalyst in said reaction system by contact of deactivated catalyst with hydrogen peroxide in the presence of the olefin while continuing the epoxidation reaction to form the reaction product.
