Vanilic Acid Article 2200431 by Markus Stöckl, Siegfried R. Waldvogel, and co-workers demonstrates a new method how to obtain selectively vanillic acid, flavouring agent antioxidant, from side-stream lignins degradation using electrochemically generated ferrate as oxidizer. In times of climate changes the utilization relevant bio-based lignin renewable feedstock for fine chemicals is considered...

Lignin depolymerisation has received considerable attention recently due to the pressing need to find sustainable alternatives to fossil fuel feedstock to produce chemicals and fuels. Two types of interunit linkages (C–C and C–O linkages) link several aromatic units in the structure of lignin. Between these two inter-unit linkages, the bond energies of C–C linkages are higher than that of C–O l...
