O knihe
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 ¿R, excess molar viscosity ¿E and excess molar Gibbs free energy of activation of viscous flow ¿G*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, ¿R was positive over the whole mole fraction range, while VE, ¿E and ¿G*E show a negative deviation.The results obtained for these binary mixtures suggest two types of molecular interactions. One is the formation of new stable complexes between the sulfone group of sulfolane and the hydroxyl group of alcohols and the second is related to the participation in destroying the mixture structure and forming a new structure.Excess molar quantities of these binary mixtures were found to be affected directly by the position of hydroxyl group and the steric associated with the methyl group.
