Experimental solubilities for biphenyl in supercritical CO//2 at elevated pressures are presented in addition to the pressure-temperature projection of the three-phase, solid-liquid-gas equilibrium line for this mixture. Interpretation of the experimental phase equilibrium behavior is accomplished using a thermodynamic model based upon the Peng-Robinson equation of state. The model is then used to predict phase equilibrium behavior to describe a promising method for separating solids dissolved in supercritical-fluid solvents.
