Viscosities of some n-alkoxyethanols with ethyl tert-butyl ether at TÂ =Â (293.15, 298.15 and 303.15) K

Viscosities at T = (293.15, 298.15, and 303.15) K in the binary mixtures of ethyl tert-butyl ether with 2-methoxyethanol, 2-(2-methoxyethoxy)ethanol and 2-[2-(2-methoxyethoxy)ethoxy]ethanol have been measured as a function of composition. From the experimental data, deviations in the viscosity from a mole fraction average and excess energies of activation for viscous flow have been calculated. The viscosity data were correlated with equations of Grunberg and Nissan, Auslaender, and McAllister. The results for Δlnη and ΔG⁎E are discussed on the basis of intermolecular interactions between the components of the analysed mixtures.
