生物基平台分子2,5-呋喃二甲酸的制备研究进展

Progress on Synthesis of Bio-Based Platform Molecular 2,5-Furandicarboxylic Acid

2,5-呋喃二甲酸(FDCA)被认为是对苯二甲酸的潜在替代物,可以作为多种绿色聚合物的单体,受到广泛关注。采用5-羟甲基糠醛(HMF)选择氧化制备FDCA是目前较为有效的方法。综述了HMF选择氧化制备FDCA的研究进展,并着重分析了HMF选择氧化制备FDCA的多相催化体系(包括Ru、Pt、Au、Pd贵金属和非贵金属催化剂)。分析了不同催化体系的问题和难点,对其今后的研究方向提供了建议,制备高活性和高稳定性的催化剂是该研究的重点,同时合理评估有碱和无碱体系的经济性也是放大生产的关键。

2,5-furandicarboxylic(FDCA)is a potential substitute for petroleum-derived terephthalic acid,and has been considered as a good precursor for producing green polymers,which have got wide attention.Aerobic oxidation of HMF provides an efficient route to synthesis of FDCA.Research progress about preparations from 5-hydroxymethyl furfural(HMF)to 2,5-Furandicarboxylic acid(FDCA),is overviewed,and present researches mainly focus on preparing supported Ru,Pt,Au,Pd and non-noble catalysts.Problems and difficulties in the preparation process are analyzed to provide advices for the further research.It is recommended that future works should be focused on,but not limited to,the preparation of highly active and stable catalysts,and reasonable evaluation between basic and base-free system is also the key of industrialization.
