摘要

The density ρ and speed of sound u of the binary mixtures of ethylenediamine (EDA) with alcohols (1-hexanol, 1-octanol, and 1-decanol) were measured at temperatures from (293.15 to 313.15) K and viscosity η at (298.15 to 308.15) K over the entire composition range and at atmospheric pressure. Using the experimental values of density, viscosity and speed of sound, the excess molar volume VmE, viscosity deviation Δη, deviation in speed of sound u ~D, deviation in isentropic compressibility Δκ _s were calculated. These results were fitted to the Redlich-Kister type polynomial equation. The variations of these excess parameters with composition were discussed from the viewpoint of intermolecular interactions in these mixtures. The excess properties are found to be either positive or negative depending on the molecular interactions and the nature of liquid mixtures. Further, the viscosity data have been used and analyzed in terms of Heric-Brewer and McAllister models.
