摘要

木质素是自然界中最丰富的可再生芳香资源。本文报道了一种新的生物精炼厂，通过两步法从木质素中生产苯甲酸。首先将还原催化分馏得到的木质素单体在多孔CoMoS （CoMoS- p）催化剂上加氢脱氧为烷基苯，CoMoS- p的多孔结构显著提高了加氢脱氧反应活性。然后以氧为氧化剂，在NHPI/Mn(OAc)2上氧化烷基苯生成苯甲酸。结果表明，从1克松木木质素中可以得到54毫克苯甲酸。

Production of benzoic acid from wood lignin

Lignin is the most abundant renewable aromatic recourses in nature. Herein we report a new biorefinery for the production of benzoic acid from lignin through a two-steps strategy. First the Reductive-catalytic-fractionation-obtained lignin monomers was hydro-deoxygenated to alkylbenzenes over a porous CoMoS (CoMoS-P) catalyst, the porous structure of CoMoS-P significantly improved the hydrodeoxygenation reactivity. Then alkylbenzenes was oxidized to benzoic acid over NHPI/Mn(OAc)2 with O2 as the oxidant. For a result, 54 mg of benzoic acid can be obtained from 1 g of pine wood lignin.
