Abstract
The paper presents a general approach based on the hypothesis of field mixing designed to describe properties of binary mixtures around critical points, including the region of two-phase states. The efficacy of the technique is illustrated by derivation of an analytic equation for boundary curves of a binary mixture. The shapes of these curves are largely determined by the critical lines T c(x) and P c(x). Given the shapes of these curves, one can easily estimate the maximum pressure at which two-phase equilibrium is possible, and the width of the retrograde condensation region.
