聚2,5-呋喃二甲酸乙二醇酯的合成研究进展

Research Progress in Synthesis of Bio-Based Poly(Ethylene 2,5-Furandicarboxylate)

摘要:

近年来石油基聚酯材料的大规模生产与应用带来了一系列的资源、能源及环境问题，以生物质资源为原料制备生物基聚呋喃二甲酸乙二醇酯（PEF）已成为化工领域的研究热点。与广泛应用的聚对苯二甲酸乙二醇酯（PET）等石油基塑料相比，PEF不仅具有相近的物理性能，而且在气体阻隔性能上的优势更为明显，被认为是有望代替PET的大宗聚酯新品种。文中重点综述了PEF的合成方法研究，总结了催化剂、聚合条件及原料来源对PEF颜色和相对分子质量的影响规律，并展望了PEF未来的发展趋势和应用前景。

Abstract:

In recent years， the large-scale production and application of petroleum-based polyester materials have brought a series of problems to resource， energy， and environment. The preparation of bio-based polyethylene furandicarboxylate （PEF） from biomass resources has become a hot topic in the chemical industry. Compared with widely used petroleum-based plastics such as polyethylene terephthalate （PET）， PEF not only has similar physical properties， but also has more obvious advantages in gas barrier properties， which is considered as a perfect substitute for PET. This paper， focusing on the synthesis of PEF， summarizes the influence of catalysts， polymerization conditions， and raw material sources on the color and molecular weight of PEF， and anticipates the future development trend and application prospects of PEF.
