Abstract:

The viscosities at T = (293.15, 298.15 and 303.15) K and ultrasonic speeds at T = 298.15 K in the binary liquid mixtures of 2-methoxyethanol with diethylene glycol, triethylene glycol and tetraethylene glycol have been measured over the entire mixture compositions. From the experimental data, deviations in the viscosity (Δη), ultrasonic speed (Δu), and excess energies of activation for viscous flow (ΔG*E) 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.
