Electrochemical Behaviour of Phenols

The literature data on the electrochemical behaviour of phenol and its adsorption on various anodic materials (platinum, graphite, gold, and lead dioxide) are surveyed and the influence of the rate of application of the potential, temperature, pH, the rate of rotation of the electrode (stirring) on the maximum oxidation current of phenol and its half-wave potential is examined. The present concept concerning the mechanism of the primary electrode reaction is analysed and the possibility of the extensive oxidation of phenol is considered. The influence of a series of substituents [OH, CH₃, NO₂, Cl, C₆H₄, COOH, C₂H₅, and C(CH₃)₃] on the principal characteristics of the potentiodynamic relations is examined and the possibility of a correlation between the half-wave potentials E_1/2 of substituted phenols and the Hammett constants is analysed.
