摘要：

The vapor and liquid phase equilibrium compositions of the ternary system CF4CHF3CClF3 were measured under isothermal and isobaric conditions of 199.80 K and 3.447 and 6.895 bars, respectively, using a vapor-recirculation apparatus. In accordance with the vapor phase being described by a modified Redlich-Kwong equation of state, liquid-phase activity coefficients were calculated and compared with the values predicted by the Wilson equation from available parameters for the three binary systems. Good agreement was found. The correlation developed allows calculation of the equilibrium compositions at 199.80 K and any pressure between 1.544 and 15.272 bars. © 1979.
