title: Non-aqueous cerimetric determination of phenylhydrazides.
abstract: A non-aqueous oxidimetric method is described for the determination of some carboxylic acid phenylhydrazides with ammonium hexanitratocerate(IV) in acetonitrile. The end-points have been detected visually with chemical indicators (diphenylamine, diphenylbenzidine, Methyl Red, Malachite Green, Janus Green, Gentian Violet) and potentiometrically. The compounds are smoothly, rapidly and quantitatively oxidized with a two-electron change per hydrazino group. The method is simple, accurate, reliable and widely applicable.
