Electrochemical oxidative degradation of Kraft lignin was investigated in b
atch and flow cells on Pt, Au, Ni, Cu, DSA-O-2 and PbO2 anodes. Production
of vanillin was evaluated by means of formal kinetic analyses. Conversion a
nd chemical yields were found to be dependent mainly on the applied current
density, that is on the partial pressure of oxygen at the interface, while
the nature of the electrode influenced the reaction rates.
