Abstract
Solubility of naphthalene in water was measured at 25°C and pressures up to 200 MPa. The solubility decreased with increasing pressure. From the pressure coefficient of the solubility, the volume change ΔV accompanying the dissolution was estimated as 13.8±0.4 cm3-mol−1. Further we estimated the volume change ΔV CH accompanying hydrophobic hydration as −0.1±0.6 cm3-mol−1 using the ΔV value, the molar volume of crystalline naphthalene, and the partial molar volume of naphthalene in n-heptane. This ΔV CH is much larger (i.e., less negative) than that for hydrophobic hydration of alkyl-chain compounds and suggests that the hydration structure of naphthalene differs from that of alkyl-chain compounds.
