PCT No. PCT/JP80/00330 Sec. 371 Date Jun. 11, 1981 Sec. 102(e) Date Jun. 11, 1981 PCT Filed Dec. 26, 1980 PCT Pub. No. WO82/02197 PCT Pub. Date Jul. 8, 1982.In the technology for producing 1,2-dichloroethane by reacting ethylene with chlorine by a liquid phase reaction at 65 DEG to 160 DEG C. in 1,2-dichloroethane containing a metal chloride catalyst, there is a disadvantage of a side reaction for producing 1,1,2-trichloroethane etc. at a large ratio to cause lower yield of 1,2-dichloroethane. The present invention is to overcome the disadvantage and to produce 1,2-dichloroethane in high yield by reducing the side reaction by incorporating at least one of aromatic compounds selected from the group consisting of benzene type hydrocarbons having the formula <IMAGE> wherein R1, R2 and R3 respectively represent hydrogen atom, C1-C5 alkyl group and chlorinated derivatives thereof as a side reaction inhibitor at a ratio of at least 0.001 wt. % in the reaction medium.
