ABSTRACT. The model approach, based on the continual approximation, have been developed for calculating of dipolar and dispersion molecular interactions contributions to the functions of liquid-vapour equilibria (Gibbs energy, enthalpy, entropy) of molecular liquids, as well as to the corresponding ones of mixing. The calculations of a set of the binary mixtures, formed by nonpolar and polar components (e.g., tetrachlorometane, benzene, cyclohexane, acetone, dimethylsulfoxide) on the whole intervals of the mixtureнs composition, and in a wide interval of temperature demonstrated the quite successful agreement with experimental data. The approach developed is important too for extracting of the contributions of aggregation processes in associated liquids and mixtures.
