Abstract: Relative permittivity of binary mixtures of aniline, pyridine, and dimethylaniline in nonpolar liquids, namely benzene, tetrachloromethane, and p-xylene has been measured at v = 455 kHz for four different temperatures. The Kirkwood-Frohlich linear correlation factor g, excess molar polarization, excess Gibbs energy of mixing in these mixtures are calculated using the experimentally determined value of relative permittivity on the basis of Winkelmann-Quitzsch equation.These parameters are found to be concentration dependent indicating existence of angular correlation between the polar molecules in the nonpolar solvent.
