Production of benzoic acid from wood lignin
Lignin is the most abundant renewable aromatic resource in nature. Herein, we report a new biorefinery for the production of benzoic acid from lignin through a two-step strategy. First reductive-catalytic-fractionation-obtained lignin monomers were hydro-deoxygenated to alkylbenzenes over a porous CoMoS (CoMoS-P) catalyst, whose porous structure significantly improved the hydrodeoxygenation reactivity. Then, alkylbenzenes were oxidized to benzoic acid over NHPI/Mn(OAc)<sub>2</sub> with O<sub>2</sub> as the oxidant. Using this biorefinery, 54 mg of benzoic acid can be obtained from 1 g of pine wood lignin.
