• The validity of the Patel-Teja equation of state was investigated for solid/supercritical fluid equilibrium systems. It was indicated that the binary interaction parameter ka12 depends strongly on temperature and pressure, and can be correlated well with mixture density of the vapor phase within the temperature range of interest. A similar relationship still remains between ka12 and solvent density. As a first approximation, linear solvent-density dependent ka12 function was used for the solubility calculation. This treatment yields a substantial improvement. The cross parameter was then generalized reasonably well by a linear solvent-density function for binary systems containing a specific solid component. Moreover, it was shown that the solid/supercritical fluid equilibrium data can be correlated by using a quadratic solvent-density dependent ka12 function with a grand AAD lower than 10%.
