Abstract
A continuous process for the production of dichlorohydrin by the reaction of allyl chloride, water and chlorine in a reaction zone comprising a first reaction stage, a final reaction stage and optionally at least one intermediate reaction stage, where the reaction mixture from at least one reaction stage is electrodialyzed in at least one electrodialysis zone to remove ions formed during the reaction, whereas at least a portion of the reaction product from said final reaction stage is passed to the concentrate inlet of said at least one electrodialysis zone, and withdrawing an ion-containing reaction product concentrate stream from said electrodialysis zone, whereby any dichlorohydrin which passes into the concentrate stream in said at least one electrodialysis zone may be recovered.
