Abstract

Abstract: At present, the biggest problem in lignin research is how to achieve efficient depolymerization of lignin, which is mainly due to the structural instability of lignin. In view of this problem, the natural structure of lignin, the structural changes of lignin in the process of separation and depolymerization were summarized and the specific effects of structural changes of lignin on the depolymerization process were also discussed. Literature survey shows that maintaining the structural integrity of lignin plays a key role in promoting the depolymerization of lignin, and put forward the prospect of the development trend of lignin depolymerization.

Key words: Lignin, β-O-4 bond, Separation, Depolymerization

摘要： 目前木质素研究中最大的问题是难以实现木质素的高效解聚，木质素的结构不稳定性是产生此问题的主要原因之一。针对此问题，介绍了木质素的天然结构，总结了分离过程和解聚过程中木质素的结构变化，并分析了木质素的结构变化对解聚过程的具体影响。结果表明，保持木质素的结构完整性对木质素解聚起到很好的促进作用，并提出了对木质素解聚发展趋势的展望。

关键词: 木质素, β-O-4, 分离, 解聚
