The solubility of palmitic acid has been measured in ethanol, 2-propanol, acetone, heptane, hexane, and trichloroethylene and in the azeotropic mixtures of the solvents (ethanol-heptane; hexane-ethanol; ethanol-trichloroethylene; acetone-heptane; heptane-2-propanol; acetone-hexane; hexane-2-propanol; 2-propanol-trichloroethylene), by a dynamic method, from (290 to 325) K. Solubility data in pure solvents were fitted by the Wilson, NRTL, and UNIQUAC equations and the solubility of palmitic acid in azeotropic mixtures with the NIBS/Redlich-Kister equation. For all calculated results, the root-mean-square deviations of solubility temperatures vary from (0.2 to 0.82) K, depending on the equation used. The solubility in pure solvents decreased in the order: trichloroethylene > 2-propanol > hexane > heptane > acetone > ethanol. The solubility of the palmitic acid increased in azeotropic mixtures compared to the pure solvents, except for the ethanol-trichloroethylene mixture where the solubility was similar to the one in pure trichloroethylene.
