A processes for preparing 1,1,2,3-tetrachloropropene, 2,3,3,3-tetrachloropropene, or a mixture thereof from 1,3-dichloropropene. The process may include a two successive chlorination and dehydrochlorination reactions. In a first chlorination reaction 1,3-dichloropropene is reacted with a chlorination agent to form a first chlorination reaction product including 1,1,2,3-tetrachloropropane. This first chlorination reaction product is reacted with a dehydrochlorination reagent in a first dehydrochlorination reaction to form a first dehydrochlorination reaction product including a trichloropropene. The trichloropropene containing reaction product is reacted with a chlorination agent in a second chlorination reaction to form a second chlorination reaction product including at least one of 1,1,1,2,3-pentachloropropane or 1,1,2,2,3-pentachloropropane. This reaction product is reacted with a dehydrochlorination reagent in a second dehydrochlorination reaction to form a second dehydrochlorination reaction product having 1,1,2,3-tetrachloropropene or a 2,3,3,3-tetrachloropropene.
从1,3-二氯丙烯制备1,1,2,3-四氯丙烯、2,3,3,3-四氯丙烯或它们的混合物的方法。该过程可能包括两个连续的氯化和脱氢氯反应。在第一次氯化反应中,1,3-二氯丙烯与氯化剂反应,形成包括1,1,2,3-四氯丙烷的第一次氯化反应产物。这个第一次氯化反应产物与脱氢氯试剂在第一次脱氢氯反应中反应,形成包括三氯丙烯的第一次脱氢氯反应产物。含有三氯丙烯的反应产物与氯化剂在第二次氯化反应中反应,形成包括至少一种1,1,1,2,3-五氯丙烷或1,1,2,2,3-五氯丙烷的第二次氯化反应产物。这个反应产物与脱氢氯试剂在第二次脱氢氯反应中反应,形成具有1,1,2,3-四氯丙烯或2,3,3,3-四氯丙烯的第二次脱氢氯反应产物。
