Abstract:
1. A process for the manufacture of 1,1,2,3-tetrachloropropene, the process comprising: (i) reacting 1,1,1,3-tetrachloropropane with chlorine in the presence of ferric chloride to produce crude 1,1,1,2,3-pentachloropropane; (ii) feeding the crude 1,1,1,2,3-pentachloropropane into a reaction zone, to transform the crude 1,1,1,2,3-pentachloropropane into 1,1,2,3-tetrachloropropene and hydrogen chloride by dehydrochlorination, wherein the 1,1,2,3-tetrachloropropene and hydrogen chloride are removed from the reaction zone during the course of the dehydrochlorination reaction; and (iii) collecting 1,1,2,3-tetrachloropropene.
