High-Pressure Solubility of Two Typical Compounds

Abstract

High-pressure solubility of sodium chloride in water and fullerene C₆₀ in toluene, two typical pairs of solute and solvent, was measured. Bird’s-eye views of their solubility-pressure-temperature surfaces are shown. Each view consists of two surfaces of non-solvate and solvate solutes; NaCl and NaCl • 2H₂O, and C₆₀ and C₆₀• 2C₆H₅CH₃, respectively. Their high-pressure phenomena are thermodynamically discussed.
