摘要:
左旋葡聚糖酮(LGO)在有机合成领域有巨大的应用价值,快速热解生物质制取左旋葡聚糖酮是生物质能开发与利用的研究热点。目前LGO的应用主要受到其产量的限制:一是没有较好的化学合成方法,二是常规热解生物质得到的产物中左旋葡聚糖酮的含量极低,使得LGO难以大量生产。催化热解可以显著提高左旋葡聚糖酮的产率,目前用于催化热解生物质制取左旋葡聚糖酮的各类催化剂,包括液体酸、固体酸、金属氯化物、离子液体等均取得了一定的成果,但效果差异明显,因此分析了不同催化剂间的优势与劣势,并对以后的工作进行了展望。

Abstract:
Levoglucosenone (LGO) has great applicable value in the field of organic synthesis. The rapid pyrolysis of biomass to produce LGO is a research hotspot in the development and utilization of biomass energy. The application of LGO is mainly limited by its yield: first, it is difficult to prepare LGO by chemical synthesis, and second, the content of LGO in the products obtained by conventional pyrolysis biomass is extremely low, making LGO challenge to produce in large quantities. Catalytic pyrolysis can significantly increase the yield of LGO. Currently, various catalysts which used to prepare LGO, including liquid acid, solid acid, metal chloride and ionic liquid, have achieved evident results, but the effects are individually different. The difference in catalytic effect of various catalysts are analyzed, and a brief conclusion for the challenge in this topic is provided.
Key words: levoglucosenone, biomass, catalytic pyrolysis, catalyst, solid acids, ionic liquids
