New dimensionally consistent modified solvate complex models are derived to correlate solubilities of solids in supercritical fluids both in the presence and absence of entrainers (cosolvents). These models are compared against the standard solvate complex models [J. Chrastil, J. Phys. Chem. 86 (1982) 3016-3021; J.C. Gonzalez, M.R. Vieytes, A.M. Botana, J.M. Vieites, L.M. Botana, J.

Res. 27 (1988) 1551-1553] by correlating the solubilities of 13 binary and 12 ternary systems. Though the newly derived models are not significantly better than the standard models in predicting the solubilities, they are dimensionally consistent. (C) 2009 Elsevier B.V. All rights reserved.
