Enthalpies and entropies of dissolution in acetonitrile, propan-2-ol and ethyl acetate were determined from the results of temperature dependence of solubility for 5-(2-nitro phenyl)-2-furyl oxime, 5-(3-nitro phenyl)-2-furyl oxime and 5-(4-nitro phenyl)-2-furyl oxime. Sublimation enthalpies and entropies were determined using integral effusion Knudsen method; adjustment of these values to 298K was conducted. Using these values the thermodynamic properties of solvation in the investigated systems were calculated. The influence of physical properties of the solvent on dissolution of the investigated compounds was analyzed.
