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.
