Abstract
We measured solubilities of several inorganic and organic compounds at high pressures up to 400 MPa, and temperatures between 273 and 323 K. For this purpose, care should be exercised for instrumentation. The results are shown for aqueous solutions of NaCl, NaCl·2H2O, CsCl, NH4Cl, toluene, anthracene, phenanthrene, and amino acids (Gly, Ala, Val, Leu, and Ile). In addition, we determined the solubility of C60 in n-hexane. The data for an individual system served to elucidate the mechanism of dissolution. For example, the data for toluene, anthracene, and phenanthrene in water provided insight into hydrophobic hydration.
