METHOD FOR PRODUCING CHLORINE-CONTAINING OLEFIN

PROBLEM TO BE SOLVED: To efficiently produce 1220xa using raw material having satisfactory gettability. SOLUTION: By (the third step) where 1,1,1,2,3,3-hexachloropropane (230da) is subjected to dehydrochlorination with a liquid phase in the presence of a lewis acid catalyst, the problem is solved. The 230da can be produced by subjecting the 1,1,3,3-pentachloropropane (240fa) to dehydrochlorination in a liquid phase in the presence of a lewis acid catalyst so as to be converted into 1,1,3,3-tetrachloropropene(1230za)(the first step), and next subjecting the 1230za to chlorination with chlorine (Cl2) at a liquid phase in the presence of a lewis acid catalyst (the second step). The fact that the reaction of the first to third steps can be performed in one pot multistep reaction utilizing all the same lewis acid catalyst has been found. As the lewis acid activity, aluminum chloride and ferric chloride are particularly suitably adopted. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT
