Abstract
The invention relates to a process for the production of dichlorohydrin which comprises reacting allylchloride, water and chlorine in a reaction zone to form an aqueous solution comprising dichlorohydrin and chlorinated organic byproducts, and contacting the aqueous solution with 1,2,3-trichloropropane to obtain an aqueous layer comprising the dichlorohydrin and an organic layer comprising the trichloropropane and chlorinated organic byproducts, separating both layers and recovering the dichlorohydrin.
