Decorated lattice gas model for supercritical solubility
Journal Article

· J. Phys. Chem.; (United States)
The authors describe a self-consistent nonclassical model for supercritical solubility enhancement near the solvent's critical point. A Widom-Wheeler-Mermin decorated lattice gas transformation is used to obtain properties of a dilute supercritical solution from known properties of the pure solvent. Phase equilibria between the solution and the additional solid or liquid phase are described. A semiquantitative representation of solubility data for three different solute-solvent pairs at several temperatures has been obtained. Infinite-dilution partial molal volumes based on parameter sets obtained from fits to solubility data do not agree very well with experiment.
