Densities, viscosities and relative permittivities of some n-alkoxyethanols with sulfolane at TÂ =Â 303.15Â K

Densities, viscosities and relative permittivities, at T = 303.15 K, in the binary mixtures of sulfolane with 2-methoxyethanol, 2-ethoxyethanol, 2-propoxyethanol and 2-buthoxyethanol have been measured as a function of composition. From the experimental data excess molar volumes, deviations in the viscosity, and the deviations in the relative permittivity from a mole fraction average have been calculated. The viscosity data were correlated with equations of Hind et al., Grunberg and Nissan, Frenkel, and McAllister. The results are discussed in terms of intermolecular interactions and structure of studied binary mixtures.
