摘　　要：石化基材料生产消耗大量不可再生资源,并对环境造成一定程度污染。而利用可再生资源生产的生物基材料性能可以与石化基材料相媲美,符合绿色、低碳、环保的发展理念,为实现“碳达峰、碳中和”的目标提供强有力的技术支撑。近年来,随着国内外政策对生物基材料的支持,生物基材料已成为国内外争相发展的新材料,为生物基材料行业的发展提供了良好的契机。利用生物法生产的生物基材料核心单体具有生产条件温和、价格低廉、绿色环保等优点,但发酵液内成分复杂以及单体浓度偏低,导致分离难度增加,严重制约了生物基材料整个行业的发展。生物基材料生产要求单体纯度高,少量杂质会影响生物基材料的外观性能。现有的生物基材料核心单体的分离研究及应用中,充分发挥化工分离技术的优势,开发出了获得高纯度生物基材料核心单体的分离纯化工艺。本综述介绍了生物基材料的生产现状,综述了近年来几种应用广泛的生物基材料核心单体分离纯化技术的研究进展,分析了目前分离技术的优缺点,最后对生物基材料核心单体分离纯化技术的发展趋势进行了展望。要点:(1)介绍了目前全球生物基材料行业的生产状况,以及对生物基材料核心单体的需求。(2)阐述了目前生物基材料核心单体分离面临的问题。(3)总结了生物基材料核心单体的分离纯化技术,对未来生物基材料核心单体的分离进行了展望。The production of petrochemical-based materials consumes large amounts of non-renewable resources and cause a certain degree of pollution to the environment.The performance of bio-based materials produced by renewable resources can be comparable to that of petrochemical based materials,which is in line with the development concept of green,low-carbon and environmental protection,and provides strong technical support for the realization of the goal of carbon peaking and carbon neutrality.In recent years,with the domestic and international policies tilted to the bio-based materials industry,bio-based materials have become a new material for domestic and international development,providing a good opportunity for the development of bio-based materials industry.The core monomer of bio-based materials produced by biological method has the advantages of mild production conditions,low price,and green environmental protection.But the complex composition within the fermentation broth as well as the low concentration of monomers and the difficulty of separation have seriously restricted the development of the whole industry of bio-based materials.The production of bio-based materials requires high-purity monomers,and a small amount of impurities affect the appearance and performance of biobased materials.The existing research and application of separation of core monomers of bio-based materials has developed the process of obtaining high purity separation and purification of core monomers of bio-based materials by taking full advantage of chemical separation technology.This review briefly introduces the current status of the production of bio-based materials,reviews the research progress of several widely used separation and purification technologies for core monomers of bio-based materials in recent years,analyzes the advantages and disadvantages of current separation technologies.Finally providing an outlook on the development trend of separation and purification technologies for core monomers of bio-based materials.Key l
