Mechanochemical degradation of lignin and wood by solvent-free grinding in a reactive medium
… Searching for alternative approaches, we wondered about mechanochemical strategies for
the degradation of lignin. In general, those have been known for a long time, but commonly they
were applied for particle size reduction as a pretreatment for a chemical depolymerisation
process performed under reaction conditions involving solvents in combination with elevated
pressure and/or … Here, we describe the initial fine-tuning of the ball milling process using
lignin model compounds and demonstrate the applicability of the method for the degradation of …

A mechanochemical approach for the cleavage of β-O-4-linkages in lignin is reported. The method is transition metal- and solvent-free, requires only inexpensive reagents, and tolerates the presence of water and standard reagent impurities.
