چکیده مقاله:
Thermodynamic and transport properties are essential in process design and operation. Density and viscosity of the multicomponent mixtures are required in many chemical engineering calculations involving fluid flow, heat, and mass transfer. [1] The experimental data of excess thermodynamic properties of the liquid mixtures provide useful information about molecular interactions. Excess molar volumes (VE), deviations in the viscosity (Δη) for the mixtures were derived from the experimental data. Densities, viscosities and derived properties for binary and ternary mixtures consist of Benzene, Cyclohexane and N,N-Dimethyl acetamide were measured at temperatures of 298.15 K in the whole range of mole fractions. The measured data and calculated values of all systems are in good agreement with literature and Redlich-Kister and the Cibulka equations.
