Thermodynamics of the solubility of 4-acetylbenzoic acid in different solvents from 303.15 to 473.15Â K

► The new solubility data of 4-acetylbenzoic acid have been investigated. ► The solubility data were determination in different solvents with high temperature. ► The relativity coefficients (R2) of the empirical formula were above 0.99. ► The thermodynamic model correlates the solubility data in good agreement. ► The thermodynamic parameters (ΔsolH and ΔsolS) of 4-acetylbenzoic acid were established.
