“…at the solvent's critical condition, plays an important role in the solvation thermodynamics of dilute mixtures at near-critical conditions by determining the asymptotic behavior of the vapor-liquid distribution factor (Japas and Levelt Sengers, 1989), Henry's constant (Japas and Levelt Sengers, 1989;, the solubility enhancement (Levelt Sengers, 1991b;Chialvo and Cummings, 1994), and the initial departure of the critical line from the critical point of the pure solvent (Chang et al, 1984). If valid for orthobaric regions away from the solvent's critical point, these asymptotic expressions become useful linear relationships for correlation purposes because they involve only the solvent's thermodynamic properties and the initial slope of the critical line that depends on the solute-solvent molecular asymmetry (Japas and Levelt Sengers, 1989).…”
