FIELD: chemistry.
SUBSTANCE: epichlorohydrin is prepared by reacting allyl chloride with an oxidizing agent in the presence of a titanium silicalite catalyst. As the oxidizing agent, a solution of hydroperoxide in methanol is used at the mass ratio of hydroperoxide and methanol (0.16-0.53):1, and the weight ratio of allyl chloride to the solution of hydroperoxide in methanol is (0.37-0.91):1. The subsequent separation of the reaction products is also described.
EFFECT: increasing the selectivity of the allyl chloride epoxidation process by completely eliminating water from the composition of the reacting components and removing water from the recycled streams of allyl chloride and methanol.
