Solubilities of benzene and diphenyl in (t-butyl alcohol + water) and hydrophobic interaction

Abstract

The solubilities of benzene and diphenyl in mixed solvents oft-butyl alcohol (TBA) and water atT= (298.15, 303.15, 308.15, and 313.15) K have been determined by spectrophotometry. The mole fractions of TBA in the mixed solvent arex= (0, 0.010, 0.020, 0.030, 0.040, 0.045, 0.050, 0.060, 0.080, and 0.150), respectively. The standard Gibbs energies of solution of benzene and diphenyl have been calculated based on the solubility data. The hydrophobic interaction (HI) for the pair benzene–benzene in the mixed solvent has also been calculated and discussed.
