Density, excess molar volumes, viscosities, for binary and ternary mixtures of {Cyclohexanone(1)+ N,N-dimethylacetamide(2) + N,N-diethylethanolamine(3) at 298.15, 308.15 and 318.15 K:Anexperimental and theoretical study

Densities ρ, viscosities η, of the binary and ternary mixturesformed by cyclohexanone + N,N -dimethylacetamide + N,N -diethylethanolamine were measured at (298.15, 308.15, and318.15) K for the liquid region and at ambient pressure for thewhole composition ranges. The excess molar volumes VmE ,viscosity deviations Δη , were calculated from experimentaldensities. The excess molar volumes are positive over the molefraction range for binary mixtures of cyclohexanone(1) + N,N -dimethylacetamide (2) and N,N-dimethylactamide (2) + N,N -diethylethanolamine (3) and increase with increasing temperaturesfrom (298.15 to 318.15) K. The excess molar volumes ofcyclohexanone (1) + N,N -diethylethanolamine (3) are S-shapeddependence on composition with negative values in the N,N -diethylethanolamine rich-region and positive values at theopposite extreme and increase with increasing temperatures from(298.15 to 318.15) K. The excess molar volumes are positive overthe whole mole fraction ranges for the ternary mixtures at alltemperatures. Viscosity deviations are negative over the molefraction range for all binary and ternary mixtures and decreasewith increasing temperatures from (298.15 to 318.15) K. Theexperimental data of constitute were correlated as a function of themole fraction by using the Redlich–Kister equation for binaryand , Cibulka, Jasinski and Malanowski , Singe et al, Pintos et al ,Calvo et al, Kohler, and Jacob - Fitzner for ternary mixture,respectively. McAllister's three body, Hind, and Nissan–Grunbergmodels were used for correlating the kinematic and dynamicviscosity of binary mixtures. The experimental data of theconstitute binaries are analyzed to discuss the nature and strengthof intermolecular interactions in these mixtures
