Abstract
The present invention provides an improved process for producing 1,1,2,3-tetrachloropropene. By using a first reactive distillation column for HCC-250fb dehydrochlorination, and a second reactive distillation column for HCC-240db dehydrochlorination/HCC-1230xf isomerization, the 1,1,2,3-tetrachloropropene manufacturing process can be greatly simplified, resulting in reduced equipment use, energy use, as well as increased productivity.
