The electrochemical oxidation of 2,6-dichloro-1,4-phenylenediamine.

The electrochemical oxidation of 2,6-dichloro-1,4-phenylenediamine was studied at a glassy carbon electrode in a 50 vol% methanol-water mixture containing 0.1M HClO(4). Single sweep voltammograms are compared with curves obtained by digital simulation. Characteristic reaction parameters, such as formal potentials, charge transfer coefficients, rate constants of the electrochemical and the chemical steps, and diffusion coefficients, were determined from potential-step experiments in combination with a simulation-curvefitting routine.
