摘要：
The invention relates to a continuous process for the production of an aqueous solution of dichlorohydrin by the reaction of allyl chloride, water and chlorine in a reaction zone which comprises:
a) electrodialyzing a significant part of the reaction mixture in an electrodialysis zone to afford (1) a concentrate stream having a chloride content higher than the concentrate inlet feed to said electrodialysis zone, and (2) a diluate stream containing dichlorohydrin and having a lower chloride content than said reaction mixture electrodialysis feed,
b) neutralizing a substantial portion of the hydrogen ions in the concentrate stream by the addition of a basic substance,
c) withdrawing a portion of said neutralized concentrate stream, and
d) recycling said diluate stream from said electrodialysis zone to said reaction zone.
