抄録

The solubilities of oxygen and nitrogen in acetone-water mixed solvent were measured at 20, 30 and 40°C. Among these solubility values except for nitrogen at 40°C, maximum and minimum values exist in the composition range of about xA<0.1, and the solubilities increased monotonously against acetone mole fraction of mixed solvent (xA) in the range of about xA>0.1.<BR>For these systems, the similarity was recognized between the excess solubility on the Ostwald coefficient expression basis and the ratio of the excess molar volume to the ideal one in the composition range of 0.2<φA<1.0.
