Abstract
The cubic equation of state having three constants, recently proposed by Yu et al., was applied to correlate the solubilities of solid components in supercritical fluids and the entrainer effect on solubilities. Three kinds of mixing rules for the constants (conventional mixing rules with one binary interaction parameter, those with two parameters, and local composition mixing rules) were adopted here and their applicabilities were examined. The solubilities and the entrainer effect can be successfully correlated by using the conventional mixing rules with two parameters and the local composition mixing rules with two parameters. However, it should be noted that the conventional mixing rules with two parameters give the best results for the system of which the solubility is very small near infinite dilution.
