Standard thermodynamic properties of solutes in supercritical solvents: simulation and theory

We report a modified simulation procedure to calculate partial molar quantities of dilute solutions in supercritical fluids through the Krichevskii function. This procedure circumvents the difficulties posed by the very large solvent compressibility and expansivity in the near-critical region of the...

Description
Summary:We report a modified simulation procedure to calculate partial molar quantities of dilute solutions in supercritical fluids through the Krichevskii function. This procedure circumvents the difficulties posed by the very large solvent compressibility and expansivity in the near-critical region of the solutions where other simulation procedures cannot be used.
