生物质衍生芳香族含氧化合物中C—O键断裂研究进展
Cleavage of C—O bonds in biomass-derived aromatic oxygenates
摘要
Abstract
Lignocellulosic biomasses contain aromatic ring structures but have high oxygen contents.The key issue for the high value utilization of biomass-derived aromatic oxygenates is the activation and breaking of C—O bonds.There are various types of C—O bonds in biomass-derived aromatic oxygenated compounds,mainly including Caryl—O(H)bonds connecting the carbon of the aromatic ring with the hydroxy-oxygen,ether bonds Caryl—O—CH3,and C=O bonds in the side chain of the aromatic ring.Catalytic hydrodeoxygenation(HDO)is an effective way for cleavage of C—O bonds of aromatic oxygenated compounds.This paper reviews the current research status of complete C—O bond cleavage and selective C—O bond cleavage of biomass-derived aromatic oxygenates,and describes the catalytic cleavage mechanism of C—O bond for typical aromatic oxygenates such as phenol,methylphenol,anisole,guaiacol,eugenol and vanillin.The roles of catalyst properties and structures such as hydrogenation ability,oxophilicity,acid sites,electronic structure and metal sites on C—O bond cleavage of aromatic oxygenated compounds are analyzed.Furthermore,some key issues and research focuses on the C—O bond breaking of aromatic oxygenated compounds are proposed.关键词
