Abstract: Two equations of (γ/χ)χ=0 ——a modified Kikic-Renon equation and a Valentin-Guiochon equation——have been studied. Values of γ_1~∞and (dlnγ_1/dχ_1)χ=0 by these two equations for 29 binary systems have been calculated from GLC data, the parameters in some models of excess Gibbs free energy evaluated and the vapor-liquid equilibrium date predicted. The results are satisfactory.

摘要： Two equations of (γ/χ)χ=0 ——a modified Kikic-Renon equation and a Valentin-Guiochon equation——have been studied. Values of γ_1~∞and (dlnγ_1/dχ_1)χ=0 by these two equations for 29 binary systems have been calculated from GLC data, the parameters in some models of excess Gibbs free energy evaluated and the vapor-liquid equilibrium date predicted. The results are satisfactory.
