Abstract

The oxidation of benzidine, o-tolidine, and o-dianisidine with chloramine T and N-bromosuccinimide was studied, the stoichiometry was established, and a mechanism was proposed. An extraction-photometric determination of these diamines was developed, based on the reaction with excess chloramine T or N-bromosuccinimide and the measurement of the absorbance of the N,N′-dihalogeno-diphenoquinonediimines formed, after their extraction into chloroform.
