Abstract

Depolymerization of purified organosolv eucalyptus wood lignin by heterogeneous catalysts, cobalt polyphosphate (CoP2O6) and calcium phosphate (β-CaP2O6) was investigated. A total syringol yield of 16.7% was achieved with β-CaP2O6 in a methanol-water (50/50, w/w) solvent system after depolymerization at 300 °C for 1 h, showing the selectivity of the catalyst. © 2015 The Royal Society of Chemistry.
