A new thermodynamic formalism has been developed for the analysis of the phase behaviour of two-component fluids. Azeotropy and critical pressure maxima or minima in binary fluids have been interpreted as bifurcations of two-phase equilibria and critical points, respectively. The analogous approach has been applied to some boundary states: hypercritical and isolated critical points, critical pressure step-points. The thermodynamic conditions of these states have been derived for the first time by a uniform way. |
