Density, viscosity and speed of sound of binary liquid mixtures of sulpholane with aliphatic amines at T =308.15 K

Experimental data on density, viscosity and speed of sound have been studied for the binary mixtures of sulpholane with diethylamine, n-propylamine, n-butylamine and tert-butylamine at 308.15 K. Excess molar volume, deviations in viscosity and isentropic compressibility have been computed from this data. The computed quantities have been fitted to the Redlich-Kister equation to derive the binary coefficients and to estimate the standard deviations. All mixtures show negative deviations for excess molar volume, deviations in viscosity and isentropic compressibility. The results have been interpreted on the basis of intermolecular interactions between unlike molecules.
