Abstract [en]

Thermodynamics of ortho-, meta- and para-hydroxybenzoic acid have been investigated. Thermodynamic data were acquired through determination of solubility, enthalpy of fusion and melting temperature. The solubility of polymorphic and solvated modifications of the isomers have been determined by comprehensive measurements between 10 and 50°C in acetonitrile, acetic acid and acetone. For each isomer and modification a strong correlation was obtained between solubility and the van't Hoff enthalpy of solution. These trends were attributed to both solution and solid-state properties. The observed correlations could also be used to differentiate between solid phases.
