Typical solubility behavior in supercritical fluids (SCF) has been described in terms of density effects, functional group, and entrainer effects. Phase diagrams of SCF are reviewed for binary mixtures with and without solid phases, by showing typical three-dimensional phase diagrams. Pressure - composition diagrams in SCF are classified from the view point of good and poor solvents. The thermodynamic stability analysis is shown for illustration of complex phase behavior of SFC including vapor-liquid, liquid-liquid, solid-vapor, or solid-liquid equilibria. The historical view of the mixing rules in equations of state of mixtures is outlined. Computer simulation techniques and their role on SCF are touched on.
