Abstract: Intermolecular interactions occurring in pyridine base —n-butanol —benzene systems were investigated by the Job's method of continuous variations. Dielectric constants, densities, and refractive indices of the solutions were determined. The densities and refractive indices were additive properties of the examined systems. Deviations of the dielectric constants Δε from the additivity were due to the formation of the hydrogen-bonded complexes. It is shown that there is a relation between Δε values of the solutions, in which 1 1 complexes are exclusively formed, and pK_a values of the corresponding pyridine bases.
