ABSTRACT

The thermodynamic and transport properties of aqueous alkanediols systems at atmospheric pressure were studied over the whole concentration range using the experimental values of density and refractive index at temperatures of 288.15 to 318.15 K with 5 K interval, viscosity at T = 293.15, 298.15 and 303.15 K and electrical conductivity at T = 298.15 K. The obtained data were compared with those available in literature. A detailed analysis regarding the behavior of aqueous alkanediols and interactions between the mixture components was performed using different excess thermodynamic properties. Moreover, McAllister, Grunberg-Nissan and its new proposed models were applied to predict the viscosity data. The validity of the proposed equations was assessed by comparisons between the experimental values and those obtained by the models.
