Abstract
Disclosed is a process for the dehydrochlorination of 1,1,1,3-tetrachloropropane comprising contacting 1,1,1,3,tetrachloropropane in the vapor phase in a reaction zone with a catalyst comprising iron, to produce a product mixture comprising 1,1,3-trichloro-1-propene; and recovering said 1,1,3-trichloro-1-propene from the product mixture produced. Also disclosed is a process for the dehydrochlorination of 1,1,1,3-tetrachloropropane comprising heating 1,1,1,3-tetrachloropropane in the liquid phase to produce a mixture comprising 1,1,3-trichloro-1-propene, cooling said mixture, separating hydrogen chloride from said mixture and recovering 1,1,3-trichloro-1-propene.
