Densities and viscosities of binary mixtures of N,N-dimethylformamide with toluene and methyl benzoate have been measured over the entire range of composition, at (298.15, 303.15, 308.15, and 313.15) K and at atmospheric pressure. From the experimental data, excess molar volumes (V-E) and deviations in viscosity (Delta eta) have been calculated. More-negative excess molar volumes for N,N-dimethylformamide + toluene systems are due to pi-electron donor- acceptor-type specific interactions between toluene and N,N-dimethylformamide molecules. The deviations in viscosity for N,N-dimethylformamide + toluene systems are very small. The excess molar volumes and deviations in viscosity have been fit to the Redlich-Kister polynomial equation. McAllister's three-body interaction model has also been used to correlate the kinematic viscosities of binary liquid mixtures with mole fractions.
