Abstract: A generating functional is suggested for the purpose of producing a set of integral equations for radial distribution functions of binary mixtures in the neighborhood of stability limit, i.e., spinodal. This set of integral equations is used to derive an equation of state from which it follows that the terms which are non-analytical by the total density of mixture start to play an important part in the region of thermodynamic variables where the third virial coefficient must be included.
