  A process for the production of epichlorohydrin is disclosed which comprises reacting allyl chloride, chlorine and water to form an intermediate, then rapid conversion and separation of epichloro­hydrin product; the epichlorohydrin-depleted reaction mixture is cooled and subjected to electrodialysis then reverse osmosis to concentrate and remove deleterious by-products, and at least a substantial portion of the resultant permeate is recycled to the reaction zone, thereby enabling reduced operating costs and/or improved yield.
