摘　　要：木质素作为自然界最丰富的芳香族化合物资源,通过可控的氧化解聚方式得到小分子芳香醛类化合物是实现木质素高附加值利用的重要途径。芳香醛作为重要的食用及日化香料、医药中间体、大宗化学品,目前主要通过石油化工产业链生产,以木质素生产芳香醛是具有重要研究意义和应用潜力的可再生资源利用途径。本文综述了国内外有关木质素制备芳香醛的最新研究进展,包括化学氧化解聚、电化学解聚、光催化解聚和生物催化解聚;对不同方法制备芳香醛的转化率和产率进行了对比,基于不同的解聚工艺与催化体系的特点进行评述与分析,展望未来木质素生产芳香醛的研究方向,以实现木质素的高值化利用。得出多方法耦合催化是可能进一步提高木质素生产芳香醛转化率与选择性的有效策略。Lignin as the most abundant resource of aromatic compounds in nature,can be degraded by oxidative depolymerization to produce aromatic aldehydes containing functional groups,which is an effective way to realize value-added utilization of lignin.Aromatic aldehydes are used as the important flavor compounds in food industry,synthetic dyes,perfumes,pharmaceutical intermediates and bulk chemicals,which are now mainly produced from petrochemical industry.In this review,the latest research progress of production of aromatic aldehydes from lignin is elaborated,including chemical oxidative depolymerization,electrochemical depolymerization,photocatalytic depolymerization,and biological depolymerization,especially,focusing on the conversion yield and selectivity of aldehydes to compare the cons and pros of various catalytic depolymerization process.Based on the characteristics of different catalytic depolymerization process,this paper analyzes the future research directions for the production of aromatic aldehydes from lignin.It is pointed out that existing catalytic methods still have various limitations for the large-scale industry production,and multi-method coupling is a promising strategy to further improve the aldehyde yield.Engineering Progress,2023,42(12):6576-6588.
