Abstract

Suffocating phenols: A catalyst system consisting of Pd/C and HZSM-5 shows an extremely high selectivity in removing oxygen-containing groups (hydroxyl, methoxy, ketone, alkyl[BOND]O[BOND]aryl, and aryl[BOND]O[BOND]aryl) in lignin-derived substituted phenolic monomers and dimers through a metal-acid catalyzed cascade cleavage of C[BOND]O bonds in phenolic dimers and the integrated hydrogenation and dehydration reactions in water at 473 K.
