Evaluation of Excess Molar Volumes of n -butanol with nitrobenzene-aniline-acetonitrile Binary Liquid Mixtures at Temperatures of 298.15, 303.15, 308.15, and 313.15 K

Abstract

The excess molar volumes ) of binary liquid mixture defined here: n -butanol and nitrobenzene, n -butanol and aniline, and n -butanol and acetonitrile have been determined as a function of mole fraction of n -butanol at temperatures of 298.15, 303.15, 308.15, and 313.15 K by a calibrated bi-capillary pycnometer. The were obtained as negative values over the entire composition range in the order of n -butanol + nitrobenzene, < n -butanol + aniline, and < n -butanol + acetonitrile systems. The negative magnitude of suggests the presence of specific intermolecular interaction in the three liquid mixtures.
