木质素转化为高附加值含氮化学品的研究进展

Research Progress on Conversion of Lignin to High Value-Added Nitrogen Chemicals

在自然界的可再生资源中,木质素是天然的芳香族高分子聚合物,基于木质素独特的芳香环结构,其具有生产大量化学品、生物燃料、功能材料和生物活性分子的巨大潜力。近十年的研究主要以木质素及其模型化合物为原料催化断裂结构单元间相连的C-C/C-O键以解聚为高附加值芳烃化合物。在此基础上,科研工作者希望引入氮原子生产含氮化学品以提高产物应用范围和附加值,为可再生资源利用发挥更大价值。本文主要论述了目前木质素转化为含氮化学品的研究进展。

Among the renewable resources in nature, lignin is a natural aromatic polymer. Based on its unique aromatic ring structure, lignin has great potential to produce a large number of chemicals, biofuels, functional materials and bioactive molecules. In recent years, lignin and its model compounds have been used as raw materials to catalyze the cleavage of C-C/C-O bonds between structural units and depolymerization of high value-added aromatic compounds. On this basis, researchers hope to introduce nitrogen atoms to produce nitrogen-containing chemicals to im-prove the application range and added value of products, and play a greater value in the utilization of renewable resources. In this paper, the progress in the conversion of lignin to nitrogenous chemicals was reviewed.
