Processes for isolating 1,1,1,2,3-pentachloropropane from a crude product stream containing the 1,1,1,2,3-pentachloropropane and ferric chloride. The processes may include deep distillation of the crude, treatment of the crude with a reagent that deactivates the ferric chloride followed by distillation on the deactivated crude stream, aqueous washing of the crude product stream to remove ferric chloride followed by distillation on the deactivated crude stream. Other embodiments simultaneously prepare 1,1,2,3-tetrachloroprene and 1,1,1,2,3-pentachloroprane.
从含有
1,1,1,2,3-五氯丙烷和
三氯化铁的粗产品流中分离出
1,1,1,2,3-五氯丙烷的工艺。这些工艺可包括对原油进行深层蒸馏,用一种能使
三氯化铁失活的试剂处理原油,然后对失活的原油流进行蒸馏,对原油产品流进行
水洗以除去
三氯化铁,然后对失活的原油流进行蒸馏。其他实施方案同时制备 1,1,2,3-四
氯丁二烯和 1,1,1,2,3-五
氯乙烯。
