摘要
The enthalpies of solution and dilution of aqueous solutions of sodium diclophenac were measured at 293.15–318.15 K on an isoperibolic calorimeter. The content of the electrolyte determined by its solubility did not exceed 0.035–0.057 mol/kg solvent depending on temperature. The Pitzer model was used to obtain virial coefficients that allowed us to calculate a wide range of excess thermodynamic properties of both solution and its components.
