Determination of the solubility, dissolution enthalpy and entropy of suberic acid in different solvents

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.

► The solubilities of suberic acid in different solvents are a function of temperature.
► It increases with an increase in temperature.
► The calculated solubility of suberic acid sets a good coherence with the experimental values.
► The dissolution enthalpy and entropy of pyrene were predicted using van’t Hoff equation.
