ABSTRACT:
Improved method for epoxidation of ethylenic alcohols is provided employing catalytic amounts of a titanium-glycol catalyst and a peroxide under mild conditions which provide for the continuous maintenance of an anhydrous medium during catalyst formation and during the course of the reaction. Conveniently, molecular sieves may be employed.
