Abstract: Heterogeneous indirect electrosynthesis process of benzaldehyde has been investigated using cyclic voltammetry and polarization curves. An optimum condition for preparation of benzaldehyde by indirect electrooxidation of toluenc with redox Mn~3+/Mn~2+ is given in this paper. Electrolytic regeneration Mn~3+ are made at Pt/Ti anode in “slurry” MnSO_4/H_2SO_4 medium. Current efficiency for electrolytic regeneration Mn~3+ was maintained over 88% by “double cyclic way”.
