Abstract:

Through ethenolysis the double bonds in biomass are cut off to obtain terminal ene derivatives, which is expected to bring more high value-added chemicals on biomass. This article focuses on the application of ethenolysis in biomass, briefly introduces the mechanism and development of ethenolysis, introduces ethenolysis catalyst, and expounds the research progress of ethenolysis in fat and oils, cashew shell oil, crotonate, phenylalanine and other biomass. The terminal ene derivatives obtained from these reactions can be used in lubricants, polymers, fragrances, drug intermediates and other fields. Among them, in the microwave the turnover of ethenolysis of fat and oils is up to 1561500, which is expected to be industrialized. At the same time, it is pointed out that the catalyst price is too expensive and it is difficult to recover, and the conversion rate and yield of some biomass raw materials are low. It is suggested that the following research should not only develop more economical and efficient catalysts, but also explore suitable raw materials, catalytic systems and technological processes for industrialization.

摘要：

通过乙烯复分解反应，将生物质原料中的双键切断，获得端烯化学品，为实现生物质原料制备高附加值化学品开辟了广阔的前景。本文围绕乙烯复分解反应在生物质原料的应用，简述了该反应的机理和发展，介绍了乙烯复分解催化剂，阐述了乙烯复分解反应在油脂、腰果壳油、巴豆酸酯、苯丙氨酸等生物质原料合成中的研究进展，这些反应得到的端烯化学品可用于润滑剂、聚合物、香料、药物中间体等领域，其中在微波辅助下油脂乙烯复分解反应周转数最高可达1561500，有望工业化，同时指出乙烯复分解反应存在催化剂价格偏贵且难以回收、部分生物质原料转化率和产率偏低的问题，建议接下来的研究除了开发更加经济且高效的催化剂外，还应探索合适工业化的原料、催化体系和工艺过程。
