Viscosities and densities are measured experimentally for three binary liquid mixtures of Aniline + Toluene, Aniline + o-Xylene and Aniline + Mesitylene using Ostwald’s viscometer and Specific gravity bottle at T = 303.15 K. Viscosities have also been calculated using empirical relations viz., Bingham relation, Kendall-Munroe relation, Arrhenius -Eyring relation, Croenaurer-Rothfus-Kermore relation and Gambrill relation. The validity of these correlations has been verified by respective deviations between calculated values and experimental values. These results show that positive deviations are present in all the three binary mixtures at T = 303.15 K. The results of all the relations are comparatively in good agreement with experimental results. These are used to draw the characteristics of the molecular association among the components of respective binary liquid mixtures.
