1,1,1,3,3-pentachloropropane process purge stream concentration using a secondary refluxed evaporator and secondary product recovery

摘要

A process for economically producing 1,1,1,3,3-pentachloropropane under conditions which preserve the activity of the catalyst. In a preferred embodiment, a two-stage distillation process is employed. In the two-stage process, the size of the equipment, temperature and vacuum are varied.
