Abstract. Phase behavior is of major importance in the analysis and development of applications of supercritical fluids. Different classes of phase diagrams of fluid mixtures are useful to understand mixing/demixing processes, to explore conditions at which such processes occur and to study the influence of temperature and pressure on solubility values.

The high pressure phase diagram of xenon was depicted with the aid of the degeneracy, coupling parameter, and current available experiments on the pressure-temperature plane. Supercritical fluids have intriguing behaviors at extreme pressure and temperature conditions, prompting the need for thermodynamic properties of supercritical fluid xenon (SCF) under shock compression.

The book begins with an overview of the phase diagrams of fluid mixtures (fluid = liquid, gas, or supercritical state), which can show an astonishing variety when 

As the critical temperature is approached (300 K), the density of the gas at equilibrium becomes denser, and that of the liquid becomes lower.

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points).

As shown on the phase diagram, the gas-liquid equilibrium curve is interrupted at the critical point, providing a continuum of physico chemical properties.
