摘　　要：木素是苯基丙烷结构单元构成的多芳环性高聚物,在化工原料和化学燃料的生产方面有很大的利用价值。目前木素主要的利用方法,就是通过解聚反应生产酚类单体产物,木素的解聚方法多样,其中酸催化解聚研究比较广泛。这里总结了木素在不同的酸催化剂中的研究进展以及反应机理:木素在无机酸中的催化解聚,木素在路易斯酸中的催化解聚以及木素在离子酸中的催化解聚。随后提出了木素在酸催化剂中的解聚发展展望。Lignin is a multi-aromatic ring polymer composed of phenylpropane units,which takes great value in chemical materials and fuels production.At present,the major application of lignin is to produce phenolic monomer products through depolymerization reaction.There are diverse lignin depolymerization methods,among which acid-catalyzed depolymerization is a more widely applied one.This paper summarizes research progresses and reactions of lignin depolymerization in different kinds of acid,including inorganic acid,Lewis acid,and ion acid.Finally the future development of acid-catalyzed depolymerization of lignin is discussed in the paper.
