The densities rho, and viscosities eta, of pure diethylearbonate, dimethylcarbonate, and N,N-dimethylacetamide and those of their binary and ternary mixtures have been measured at 298.15 K and atmospheric pressure over the entire range of compositions. Excess molar volumes V-123(E), viscosity deviations Delta eta(123), and excess Gibbs energy of activation G*(E)(123), were obtained from the experimental results. The values for the binary and ternary systems were fitted to Redlich-Kister's and Cibulka's type function in terms of mole fractions, respectively. McAllister's three body interaction model is used for correlating the kinematic viscosity of binary mixtures with mole fraction. The experimental data of the constitute binaries and ternary are analyzed to discuss the nature and strength of intermolecular interactions in these mixtures. (c) 2007 Elsevier B.V.
