The experimental data of densities and viscosities of the binary mixtures of morpholine with benzene, toluene, m-xylene and mesitylene have been reported over the whole composition range at (303.15 to 313.15) K at normal atmospheric pressure. Experimental data on density and viscosity have been used to derive excess properties like excess molar volumes V-E, viscosity deviations (Delta eta) and Gibbs energy of activation for viscous flow (G(E)) as a function of composition. The experimental viscosity data have been correlated with the two body empirical equations like Grunberg-Nissan, Dolezalek Schulze, Tamura Kurata, Katti Chaudhri and three body McAllister's equation. Interaction parameters D-12, G(12), T-12, and W-vis/RT have been calculated. The experimental determined values of V-E, Delta eta and G(E) were fitted to the Redlich Kister-type polynomial equation. The variation of these properties with composition and temperature of the binary mixtures are discussed in terms of intermolecular interactions between unlike molecules. (C) 2014 Elsevier B.V.
