The solubility of 3-hydroxy-2-naphthoic acid in ten commonly used solvents and binary mixtures under atmospheric pressure was determined with a gravimetric method as temperature varied from 293.15 to 333.15 K. Methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, acetone, acetic acid, methyl acetate, and ethyl acetate were used as pure solvents for 3,2-HNA, and ethanol plus n-propanol were selected as binary mixed solvents. What can be concluded is that the solubility of 3,2-HNA in all kinds of solvents increases as temperature increases. In addition, empirical equations, containing the modified Apelblat equation and λh equation, and activity coefficient models, such as the non-random two liquid (NRTL) model and the universal quasi-chemical (UNIQUAC) model, were chosen for correlation with the solubility data. The correlation results agreed with the measured data very well. Therefore, the measured results and thermodynamic study of 3-hydroxy-2-naphthoic acid will provide help for its practical industrial production.
