| Abstract:Lignin， the natural macromolecular polymer， is the third largest biomass in nature reserves and under the reserves of cellulose and chitin. Lignin contains three structural units i.e.guaiacyl， syringyl and p hydroxyphenol， which are connected by the bond of ether and CC， and ultimately formed complex chemical structures. Besides， lignin is closely associated with cellulose and hemicellulose in plants material， so it is difficult to isolate pure lignin by existing means. Pulping process is seriously affected by lignin， especially the processes of cooking and bleaching. In order to understand the chemical reaction mechanism and structural changes of lignin during pulpingprocess， the lignin model compounds should be used in the study. This paper reviews the recent developments of lignin model compounds. In addition， it particaly discusses the application of lignin model compounds in the researches of bleaching reaction mechanism and the formation of LCC in cooking process． |
