PROCESS FOR THE PRODUCTION OF CHLORINATED PROPENES

摘要

Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material. 1,1,1,2,2-pentachloropropane produced by the process is subjected to catalytic dehydrochlorination and build-up of the same within the process is avoided.

主权项

1. A process for the production of chlorinated propenes from a feedstream comprising 1,2-dichloropropane, wherein at least a portion of the pentachloropropanes produced by the process are catalytically dehydrochlorinated using at least one dehydrochlorination catalyst selected from the group consisting of aluminum chloride, antimony pentachloride, titanium tetrachloride, or a combination of these, wherein the pentachloropropanes comprise 1,1,1,2,2-pentachloropropane, and wherein the catalytic dehydrochlorination produces a stream comprising 1,1,2,3-tetrachloropropene and unreacted pentachloropropanes.
