Abstract
Process for the production of epichlorohydrin in which the chloroaliphatic impurities formed at the hypochlorination of allyl chloride to dichloropropanols are removed from the crude aqueous solution of dichloropropanols before dehydrochlorination, by extraction with a recycled organic solvent which is rich in 1,2,3-trichloropropane.
