In this book of the refractive indices, nD, densities , and viscosities of binary mixtures of sulfolane +, n- butanol+, sec-butanol +, iso-butanol +, tert-butanol +, n-propanol and isopropanol at 298.15k.From experimental data, excess molar volume VE, excess molar refractivity DeltaR, excess molar viscosity E and excess molar Gibbs free energy of activation of viscous flow DeltaG*E were calculated.From n-propanol-sulfolane and iso-propanol-sulfolane mixtures showed negative AR, but for n-butanol-sulfolane, sec-butanol-sulfolane, iso-butanol-sulfolane and tert-butanol-sulfolane, DeltaR was...
