INDIRECT ANODIC-OXIDATION OF BENZYL ALCOHOL IN THE PRESENCE OF PHASE-TRANSFER CATALYST IN A CSTER - EFFECT OF FLOW-RATE AND TEMPERATURE

The current efficiency for producing benzaldehyde, the conversion of b enzyl alcohol and the yield and selectivity of benzaldehyde were all i ndicated by experimental and theoretical results as being significantl y affected by the flow rate and the reaction temperature. The dynamic behavior of the indirect oxidation of benzyl alcohol was similar to th at of a typical series reaction in a batch reactor, as observed by app lying 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 a s 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.
