ABSTRACT

Densities and viscosities of binary mixtures of N,N-dimethylformamide (DMF) with aniline and benzonitrile have been measured at (298.15, 303.15, 308.15, and 313.15) K. From these data, excess molar volumes (VE) and deviations in viscosity () have been calculated. Negative excess molar volumes and negative deviations in viscosity for DMF + aniline systems are attributed to the interstitial accommodation of DMF molecules into clusters of aniline. Negative excess molar volumes and positive deviations in viscosity for DMF + benzonitrile systems are due to the strong specific interactions. The excess molar volumes and deviations in viscosity are fitted to the Redlich-Kister polynomial equation.
