摘要:木质素作为可再生资源被认为是最具有潜力的苯酚替代物用于制备酚醛树脂,作为制浆造纸工业副产品,木质素来源丰富且低毒,但是木质素具有三维空间网状结构,分子量大,反应活性低。到目前为止,很多方法(如热化学转化、热裂解、液化、超临界水处理、氧化、还原和水解等)用于将大分子木质素降解为小分子物质,得到的小分子物质中含有重要的化工中间体可以用来制备多种产品。本论文综述了木质素氧化降解得到酚类物质的研究现状,并展望了木质素工业化的应用前景。
Lignin is a promising substitute for phenol in phenol-formaldehyde(PF) resin formulation.It is readily available and low toxic as a by-product from the pulp and paper industry.However,lignin is a three-dimensional amorphous biopolymer with high molecular weight and low reactivity.To date,many methods such as thermochemical conversion,pyrolysis,liquefaction,supercritical water treatment,oxidation,reduction,hydrolysis,etc.have been made to degrade macromolecular lignin into lower molecular weight fractions containing useful chemicals,which are important intermediates in the chemical industry for a diversity of products.The present work discusses the potential for an increased use of lignin as a renewable raw material.A brief overview about present state of lignin oxidative degradation is given and phenolic compounds from lignin are presented,and its large-scale production is prospected.
