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.
摘要翻译：一种用于从包含二氯代醇的混合物中回收二氯代醇的方法和装置，一种或多种选自二氯丙醇，一氯代醇和/或其酯的化合物和多羟基化脂族烃化合物和/或其酯的化合物，以及任选的一种或多种包含水的物质，公开了氯化剂，催化剂和/或催化剂的酯。将混合物蒸馏或分馏以从混合物中分离包含二氯丙醇的低沸点馏分以形成包含蒸馏或分馏残余物的较高沸点馏分。汽提高沸点馏分以回收剩余的二氯代醇。优点包括为给定的蒸馏塔更有效地回收二氯代醇，避免了有利于形成重质副产品的条件减少浪费，减少回收设备的资本投入。
