Popis:	The addition of an organic cosolvent to water can increase the aqueous solubility of many hydrophobic organic compounds (HOCs). This work examines the correlations between the change of naphthalene solubility and various physicochemical properties of the cosolvent added to the system. Results show that the dielectric constant and surface tension do not correlate with the solubilization power of cosolvent toward naphthalene. The solubility parameter correlated well with increases in naphthalene solubility and therefore provides a convenient tool when screening cosolvents for their ability to enhance HOC solubility in various environmental engineering applications. Other properties investigated include the octanol/water partition coefficient, interfacial tension E{sub T}(30), viscosity, and hydrogen bonding capacities.
