Abstract:
1. A process for the synthesis of 1,1,2,3-tetrachloropropene (HCC-1230xa) using an organic starting material selected from 1,1,3-trichloropropene (HCC-1240za), 3,3,3-trichloropropene (HCC-1240zf), or mixtures thereof, and Cl 2 gas as the reactants, with a dehydrochlorination catalyst, wherein the process takes place in a single reactor system; wherein the single reactor system comprises a continuous stirred tank reactor equipped with a total condenser, and a reaction column equipped with a total condenser; wherein the reaction column is separated into four zones comprising (a) a Cl wherein the starting material is fed into the organic feed zone of the reaction column and flow downward via a liquid distributor, while an excess amount of Cl
