Abstract: Kp values experimentally found in the synthesis of vinyl chloride (I) from C₂H₂ and HCl, with HgCl₂ and active C as catalyst, were compared with the theoretical thermodynamic values. The equil. compn. in the reaction mixt. at 350-550°K. was calcd. Even at the initial mol. ratio C₂H₂:HCl = 1:1, the conversion of C₂H₂ to I decreases permanently with the increasing temp., and the conversion to 1,1-dichloroethane (II) first slightly increases and at temps. above 230° decreases rapidly. This was found to be true by expt. By comparing the theoretical calcns. with practical results in the formation of II in the excess of HCl the selective effect of the catalyst (HgCl2 on active C) was detd. in the reaction forming I.
