摘要：

Ionic association constants of pyridine N-oxide perchlorate and semiperchlorate have been determined conductometrically as well as limiting molar conductances of PyOH+ and PyOHOPy+ cations in acetonitrile. The acid dissociation constant of the protonated pyridine N-oxide and the cationic homoconjugation constant of pyridine N-oxide with conjugated cationic acid have been found from potentiometric measurements. On the bass of determined values of the equilibrium constants, a scheme of fundamental ionic equilibria in the acetonitrile solutions of the perchlorates has been suggested. © 1990.
