Summary

VAPOUR-LIQUID EQUILIBRIA MEASUREMENTS WERE MADE ON BINARY MIXTURES OF CARBON DIOXIDE WITH NORMAL AND ISOBUTANE AT 250, 260, 270 AND 280 K. BOTH LIQUID AND VAPOUR COMPOSITIONS WERE MEASURED. THE DATA WERE CORRELATED USING THE PENG-ROBINSON EQUATION OF STATE, AND VALUES ARE GIVEN FOR THE ACTIVITY COEFFICIENTS AND THE EXCESS GIBBS FREE ENERGY G. THE HEAT OF MIXING IS ESTIMATED FROM THE TEMPERATURE DEPENDENCE OF G.
