PROCESS FOR PREPARING 1,1,3-TRICHLOROPROPENE BY CONTROLLING THE MOLAR RATIO OF 1,1,3-TRICHLOROPROPENE TO 1,1,1,3-TETRACHLOROPROPANE

摘要

Disclosed is a process for preparing a chlorinated alkene, comprising contacting a chlorinated alkane with a catalyst in a dehydrochlorination zone to produce a liquid reaction mixture comprising the chlorinated alkane and the chlorinated alkene, and extracting chlorinated alkene from the reaction mixture, wherein the concentration of the chlorinated alkene in the reaction mixture present in the dehydrochlorination zone is controlled such that the molar ratio of chlorinated alkene:chlorinated alkane is from 1:99 to 50:50.
