Abstract
Excess molar volumes (VEm) and dynamic viscosities (η) for five (alkoxyethanol + propylamine) mixtures have been measured as a function of composition at 298.15 K and atmospheric pressure. The alkoxyethanols were 2-methoxyethanol, 2-(2-methoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethanol, 2-(2-butoxyethoxy)ethanol, and 2-{2-(2-methoxyethoxy)ethoxy}ethanol. The excess molar volumes VEm are all negative over the whole composition range. The viscosity data have been correlated by the methods of Kendall and Monroe, Grunberg and Nissan, Tamura and Kurata, Hind, Katti and Chaudry, and with McAllister correlations. From the experimental data, deviations in the viscosity (Δη) have been calculated. The results are discussed in terms of the interaction between components.Key words: excess volume, viscosity, binary mixtures.
