The calculation of critical states using a Corresponding States Principle is described. It is shown how a correlation of binary critical T**c-P**c behavior can lead to predictions of high pressure as well as low pressure phase equilibria and PVT properties. Critical states (including V**c-x**c behavior) of hydrocarbon systems as well as systems containing polar components have been successfully correlated using this method. The applicability of the method to asymmetric mixtures which are typical of supercritical extraction processes is examined.
