ABSTRACT:
Epichlorohydrin is prepared by the epoxidation of allyl chloride by a process which comprises irradiating an oxygen-saturated solution of allyl chloride in an aprotic solvent in the presence of an effective amount of an alpha-diketone sensitizer with the radiation of a 450 watt medium-pressure mercury lamp. Propylene oxide is prepared by a similar process by the epoxidation of propylene.
