Abstract The chlorination equilibrium of cupric oxide has been investigated using the circulation method. Within the temperature range 300—450℃, the reaction is found to take place in two stages, and the following results are obtained:2CuO(s)+Cl_2(g)=Cu_2OCl_2(s)+1/2O_2(g), (1)logK_p~Ⅰ=(3061/T)-2.228,ΔG_Ⅰ~O=-14010+10.20T.Cu_2OCl_2(s)+Cl_2(g)=2CuCl_2(s)+1/2O_2(g), (2)logK_p~Ⅱ=(2370/T)-1.90,ΔG_Ⅱ~O=-10850+8.69T.The physical properties of the intermediate compounds have been studied, and within the given temperature range, the average enthalpy of formation of the intermediate compound Cu_2OCl_2 is found to be -84900 cal./mole; and its average entropy of formation to be -51.23 e.u.
