ABSTRACT
Oxidation of toluene to benzaldehyde in the presence of the redox couple V5+/V4+ was carried out in an undivided cell where oxygen gas was continuously bubbled over the cathodic surface and the electrolyte was a mixture of aqueous H2SO4 solution containing V5+ and toluene. Some experimental conditions affecting the current efficiency for benzaldehyde production, such as H2SO4 concentration, current density, V5+ concentration and surfactants, were determined. The maximum current efficiency for benzaldehyde production at ambient temperature was 156.3% under the conditions of 11 M FI2SO4, 2.7 x 10-4 M CTAB, current density 1.25 mA cm-2 and 0.0128 M V5+.
