摘要： A continuous process for the production of dichlorohydrin by the reaction of allyl chloride, water and chlorine having substantially lower energy requirements than conventional processes, wherein the reaction mixture is subjected to reverse osmosis to concentrate the dichlorohydrin and to provide a permeate stream substantially free of dichlorohydrin, which permeate stream is recycled to the reaction.

摘要： 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.

摘要： Polyethercyclicpolyols are prepared by thermally condensing a polyol having at least three hydroxyl groups of which at least two of the hydroxyl groups are vicinal, precursors of the polyol, cyclic derivatives of the polyol, or mixtures thereof, and controlling process conditions to avoid substantial undesirable degeneration. Lower molecular weight polyethercyclicpolyols are copolymerized with epoxy resins to form higher molecular weight polyethercyclicpolyols.
