    Abstract

    The behaviour of alizarin-9-imine as an indicator in acetonitrile and pyridine media has been studied. The protonation constant in acetonitrile, KI = aHi + aH+ · aI = 10-3.4, has been determined. Organic acids, amino-acids, and aliphatic and aromatic amines have been titrated with errors below 2%. © 1983.
