Abstract
In a multistage reaction system for the preparation of dichlorohydrin by the reaction of allyl chloride, water and chlorine and where the hydrochloric acid by-product is removed by electrodialysis, increased efficiency for acid removal by electrodialysis results from at least partial neutralization of the acid in the electrodialysis concentrate receiving stream, enabling the use of smaller electrodialysis membrane area and or lower energy consumption.
