DENSITIES AND VISCOSITIES OF BINARY-LIQUID MIXTURES OF NITROBENZENE WITH CYCLOHEXANE AND N,N-DIMETHYLFORMAMIDE

Excess volume, excess viscosity, excess free energy of activation of flow, and contact interaction parameter have been computed for binary liquid mixtures of nitrobenzene with cyclohexane or N,N-dimethylformamide from density and viscosity measurements in the temperature interval of 298.15-313.15 K. The calculated quantities are discussed in terms of the nature of the molecular interactions between the components. Attempts were also made to test the validity of the viscosity models of Heric, Auslaender, and McAllister in predicting the binary viscosity data. © 1990, American Chemical Society.
