摘要

The solubilities of benzene and diphenyl in mixed solvents of tbutyl alcohol (TBA) and water with different salts have been determined at T = 298.15, 303.15, 308.15 and 313.15 K.The molar fraction of TBA [ x (TBA) ] in mixed solvent is 0.045, and the molality of the salts (ms) in mixed solvents are 0.000, 0.250, 0.500, 0.750 and 1.000 mol/kg, respectively. The standard Gibbs energies of solution of benzene and diphenyl in the mixed solvents have also been calculated based on the solubility data. The effects of different salts on the hydrophobic interaction (HI) for benzene-benzene pair in the systems were discussed.
