It is found that the expression for(γ/x)_x-o derived on the basis of Lenoir’s works should Ix differentfrom that derived by Kikic and Renon in 1976.and(lnγ_1,/x_1)_x_1=0 values have beenmeasured for 10 binary systems by gas-liquid chromatography.According to the new expression,UNIQUACparameters and the vapor-liquid eqilibrium data are evaluated.Of the six systems data available in litera-ture the predicted results are satisfactory.
