KINETICS OF THE ANODIC-OXIDATION OF BENZYL ALCOHOL IN DICHLOROMETHANE IN THE PRESENCE OF REDOX MEDIATOR AND PHASE-TRANSFER CATALYST

The kinetics of the anodic oxidation of benzyl alcohol in the two-phase system involving both, the redox mediator, OCl-/Cl-, and a phase transfer catalyst were investigated. The reaction order of the anodic oxidation of chloride ion in the aqueous phase was unity. The charge-transfer parameters, α, k20 and the exchange current density, i0, of the anodic oxidation of chloride ion in the aqueous phase were obtained. The theoretical model calculations correlated well with experimental data. The fractions of anodic surface covered by the aqueous phase were evaluated to be 0.89, 0.61, and 0.23 when the organic-to-aqueous volume ratios were 0.5, 1.0, and 2.0, respectively. © 1990 Chapman and Hall Ltd.
