摘要： 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.
