In this study, the temperature dependences of the solubility of 5-(4-methylphenyl)-2-furanpropanoic acid in various solvents were evaluated: methyl and ethyl acetate, acetonitrile, propane-1-ol, and propan-2-ol. The results of the analysis are presented in the form of linear equations according to the Schröder model, which allowed us to determine the enthalpies, entropies, and Gibbs energies of solubility at a temperature of 298.15 K. The melting points of the acid were determined using the method of differential thermal analysis, which allowed us to calculate the enthalpies, entropies, and Gibbs energies of mixing.
