Abstract: This invention relates to a method to improve 1,1,3-trichloropropene (HCC-1240za) and/or 3,3,3-trichloropropene (HCC-1240zf) selectivity in the dehydrochlorination of 1,1,1,3-tetrachloropropane (HCC-250fb). In normal practice, FeCl3 is used as the catalyst for the dehydrochlorination of HCC-250fb to produce 1,1,3-trichloropropene and/or 3,3,3-trichloropropene. Here the improvement comprises, using as the starting material, a mixture comprising HCC-250fb and Heavies generated from the reaction of CCl4 and ethylene to produce HCC-250fb, wherein the Heavies comprise one or more tetrachloropentane isomers. These compounds reduce or eliminate the formation of unwanted high boiling compounds (HBCs).

Abstract: Two methods for reducing CFC impurities and, in particular, CFC-114, in the HFO-1234ze(E) production process from the reaction of CFC-113 and HF. The first method involves subjecting an intermediate or recycle stream to separation and distillation to purge CFC-113 from the process. The second method involves operating the separation at a higher pressure avoids the formation of an azeotrope between CFC-113 and HFC-245fa. The CFC-113/HFC245fa azeotrope is discussed, as well as other optional processes for removal or mitigation of CFC-113 which include further separations that remove CFC-114 from the HFO-1234ze(E) product and/or CFC-113 from the HFC-245fa feed to produce an HFO-1234ze(E) product that is largely free from CFC-114 and other CFC impurities.
