The molar fraction of TBA [x(TBA)] in mixed solvent is 0.045, and the molality of the salts (m_s)in mixed solvents are 0.000, 0.250, 0.500, 0.750 and 1.000 mol/kg, respectively. The standard Gibbsenergies of solution of benzene and diphenyl in the mixed solvents have also been calculated basedon the solubility data. The effects of different salts on the hydrophobic interaction (HI) forbenzene-benzene pair in the systems were discussed.展开更多
