Abstract
A continuous process for the production of dichlorohydrin by the reaction of allyl chloride, water and chlorine having substantially lower energy requirements than conventional processes, wherein the reaction mixture is subjected to reverse osmosis to concentrate the dichlorohydrin and to provide a permeate stream substantially free of dichlorohydrin, which permeate stream is recycled to the reaction.
