摘要： A process and apparatus for recovering dichlorohydrins from a mixture comprising dichlorohydrins, one or more compounds selected from esters of dichlorohydrins, monochlorohydrins and/or esters thereof, and multihydroxylated- aliphatic hydrocarbon compounds and/or esters thereof, and optionally one or more substances comprising water, chlorinating agents, catalysts and/or esters of catalysts is disclosed. The mixture is distilled or fractionated to separate a lower boiling fraction comprising dichlorohydrin(s) from the mixture to form a higher boiling fraction comprising the residue of the distillation or fractionation. The higher boiling fraction is stripped to recover remaining dichlorohydrins. Advantages include more efficient recovery of dichlorohydrins for a given distillation column, less waste due to avoiding the conditions conducive to the formation of heavy byproducts, and reduced capital investment in recovery equipment.

The process includes distilling and/or fractionating a feed stream containing epichlorohydrin, dichlorohydrin(s), and one or more other substances, subjecting at least a portion of the liquid phase effluent to a dichlorohydrin dehydrochlorination process for converting residual dichlorohydrin(s) in the liquid phase effluent to epichlorohydrin, and recovering purified epichlorohydrin from the vapor phase effluent in which the distillation/fractionation pressure and/or temperature of step (1) is adjusted to retain at least 5 weight-percent epichlorohydrin in the liquid phase effluent. The apparatus for making purified epichlorohydrin includes a dehydrochlorination apparatus, a first liquid-vapor contacting apparatus, and a second liquid-vapor contacting apparatus connected to the dehydrochlorination apparatus for recycling a distillate to the dehydrochlorination apparatus. Advantages include more efficient recovery of epichlorohydrins and reduced capital investment in recovery equipment.
