ABSTRACT
The solubilities of suberic acid in methanol, ethanol, 1-propanol, 2-propanol, propanone, water, ethyl acetate and tetrahydrofuran were determined at temperatures between 283 K and 340 K. The experimental data can be well correlated by Apelblat model. The dissolution enthalpy and entropy of suberic acid were predicted from the solubility data using van't Hoff equation.
