摘　　要：大量化石资源开采和利用带来的能源安全和环境污染问题已经引起广泛关注。利用可再生资源,发展可再生能源和绿色化学品是可持续发展的重要方向。生物质是唯一可持续发展碳资源,其转化利用是实现“双碳”目标的重要途径之一。几丁质作为第二大生物质,是唯一含氮多糖;将几丁质转化制备含氮化学品具有独特的理论和应用意义。近年来,将几丁质转化制备含氮化学品取得较大进展。主要针对几丁质含氮结构特点,总结了几丁质水解生成寡聚物和单糖N-乙酰氨基葡萄糖,以及几丁质及单糖转化制备呋喃化合物、杂环含氮化学品和其他含氮化学品的最新研究进展。重点归纳了几丁质及单体催化转化制备3-乙酰氨基-5-乙酰基呋喃的进展和规律。针对这些进展,还提出了该领域存在的问题和挑战,并展望了该领域的发展方向,以期推动几丁质催化转化制备含氮化学品高质量发展,助力实现“双碳”目标。The energy security and environmental pollution issues brought about by the exploitation and utilization of large amounts of fossil resources have attracted widespread attention.The exploitation of renewable resources and the advancement of renewable energy and green chemicals are pivotal aspects of sustainable development.Biomass stands as the sole sustainable carbon resource,with its conversion and utilization representing a crucial pathway towards accomplishing the dual carbon goals.Chitin,being the second largest biomass,constitutes the sole nitrogencontaining polysaccharide.Hence,the process of converting chitin for the preparation of nitrogen-containing chemicals holds distinctive theoretical and practical significance.Remarkable strides have been made in recent years with regards to chitin conversion for the production of nitrogen-containing chemicals.This article primarily delves into the nitrogen-containing structural features of chitin,outlining the most recent research progress in chitin hydrolysis for the generation of oligomers and monosaccharide N-acetylglucosamine,the transformation of chitin and monosaccharides for the production of furan compounds,hybrid nitrogen-containing chemicals,and other nitrogen-containing chemicals.Particularly,the advancements and principles of catalytic conversion of chitin and monomers for the preparation of 3-acetylamino-5-acetylfuran are summarized.In addressing these advancements,the article also presents the existing issues and challenges,while offering a glimpse of the research direction in this field,in an effort to advance the high-quality development of chitin catalytic conversion for the preparation of nitrogen-containing chemicals and to aid in achieving the dual carbon goals.
