The current efficiency for producing benzaldehyde, the conversion of benzyl alcohol and the yield and selectivity of benzaldehyde were all indicated by experimental and theoretical results as being significantly affected by the flow rate and the reaction temperature. The dynamic behavior of the indirect oxidation of benzyl alcohol was similar to that of a typical series reaction in a batch reactor, as observed by applying a low flow rate and a large total current towards the two-phase system in a CSTER (continuous stirred tank electrolysis reactor). The rate of formation of benzaldehyde increased and the induction period as well as the power consumption decreased when the flow rate increased. In view of current efficiency, yield and selectivity of benzaldehyde, the optimum temperature being obtained at 20-degrees-C was confirmed by the experimental results.
