A new theory of dilute, multicomponent solutions has been derived by expansion about the infinite dilution limit. For dilute, binary mixtures to first order, the theory reduces to that of Debenedetti and Kumar. It is shown that models can be derived within the theory by application of conformal solution theory, fluctuation theory, or their combination. These models have been shown to be useful and accurate in test applications to solutions two solid solutes in a supercritical solvent, quantitatively reproducing the cosolute effect for which correlation with the Peng-Robinson equation of state was only partially successful. Other potential applications include solubility of gases in liquids and solid solubilities in entrained supercritical solvents.
