    • Describes an integrated process for preparing 1,2-dichloroethylenes. In the described process organic feed material, e.g., C2 - C4 aliphatic hydrocarbons and/or chlorinated derivatives of such aliphatic hydrocarbons, is introduced into a first reaction zone 10, e.g., a chlorination zone such as an oxychlorination zone, or a thermal cracking zone; first product effluent from the first reaction zone is forwarded to a second reaction zone 9; trichloroethane is introduced into the second reaction zone and into heat exchange contact with the first product effluent from the first reaction zone, which has a heat content sufficient to cause thermal dehydrochlorination of trichloroethane in the second reaction zone; and second product effluent is removed from the second reaction zone. 1,2-dichloroethylene is recovered by conventional distillation recovery methods from the second product effluent.
    • 描述了制备1,2-二氯乙烯的综合方法。 在所述方法中,将有机原料(例如C 2 -C 4脂族烃和/或这些脂族烃的氯化衍生物)引入第一反应区10,例如氯化区如氧氯化区或热裂解区 ; 来自第一反应区的第一产物流出物被转送到第二反应区9; 将三氯乙烷引入第二反应区并与来自第一反应区的第一产物流出物进行热交换接触,第一反应区的热含量足以在第二反应区引起三氯乙烷的热脱氯化氢; 并且从第二反应区域除去第二产物流出物。 通过常规蒸馏回收方法从第二产物流出物回收1,2-二氯乙烯。
