ABSTRACT:
Epoxides are produced by an integrated process involving molecular oxygen oxidation of an alkylammonium salt of a sulfonic acid-substituted anthrahydroquinone, epoxidation of an ethylenically unsaturated substrate using the hydrogen peroxide-containing product obtained by such oxidation in the presence of a titanium silicalite catalyst, and regeneration of the anthrahydroquinone by hydrogenation of the anthraquinone co-product. Oxidation and epoxidation may be performed concurrently. The alkylammonium salts have the advantage of being highly soluble in polar protic media such as water and lower alcohols.
