MEASUREMENT OF EXCESS GIBBS FREE ENERGY MODEL PARAMETERS BY CHROMATOGRAPHIC SLOPE METHOD

【摘要】 <正> 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（lnγ₁,/x₁）_x1=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.更多还原
