A two‐parameter, corresponding‐states form for direct correlation function integrals in liquids is applied to many types of systems with one substance being supercritical. This gives a quantitative correlation for volumetric behavior, pure and mixed solvent Henry's constants, and Henry's Law deviations over wide ranges of conditions using only pure‐component information and a single binary parameter. Details of the method and results are given for H 2 , N 2 , CO, CH 4 , and other gases in pure and mixed simple, polar, and aqueous solvents and coal oils. Because of its reliable predictive capability, the present approach can serve as a generator of data for parameter estimation by other models such as equations of state.
