摘要：

The solubility of azobenzene in water and aqueous alcohol solutions was determined at 5 °C intervals from 0° to 40 °C. Prom the results the thermodynamic parameters for the transfer of one mole of azobenzene from water to aqueous alcohol solution were calculated. It was found that the process was endothermic: furthermore, it was invariably accompanied by a positive unitary entropy change. The solubilizing mechanism of alcohols was explained in terms of an adduct-formation with the compound to be dissolved by means of hydrophobic interaction. © 1969 Dr. Dietrich Steinkopff Verlag.
