木质素氧化解聚制备芳香醛研究进展
Research process of preparation of aromatic aldehyde by oxidative depolymerization of lignin
摘要
Abstract
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.关键词
