Solubility in fluids close to their critical points
A feature of solubility in near-critical fluids is its strong dependence on pressure and temperature. A general thermodynamic procedure which describes the distribution of solutes between two coexisting phases, may be conveniently employed to describe solubility in near-critical fluids.

| Sumario: | A feature of solubility in near-critical fluids is its strong dependence on pressure and temperature. A general thermodynamic procedure which describes the distribution of solutes between two coexisting phases, may be conveniently employed to describe solubility in near-critical fluids. Asymptotic critical relations are a great help to evaluate data for volatile solutes, for solid solutes they help to separate contingent dependences of solubility from those which are essential. This analysis suggests there is no need to invoke the existence of critical clustering to explain the observed behaviour. © 1995 IUPAC |
