The Industrial Electrolytic Regeneration of Mn2(SO4)3 for the Oxidation of Substituted Toluene to the Corresponding Benzaldehyde

A new industrial process for the electrolytic regeneration of Mn2(SO4)3 is presented in which:– a slurry of MnSO4/Mn2(SO4)3 in 55% H2SO4 is used as a carrier,– the electrolyte is purified with an optimum mode before electrogeneration, and–a new industrial electrochemical reactor is developed for an economical electrogeneration of Mn2(SO4)3
