Research progress in synthesis of 2,5-furanedicarboxylic acid through 5-hydroxymethylfurfural route
2,5-Furanedicarboxylic acid(FDCA)is an important monomer that can be used to synthesize bio-based polyes-ters,and it currently has broad application prospects in the field of new biodegradable plastics.How to efficiently and cheaply prepare FDCA has gradually become a hot topic.This article systematically reviewed the main research progress in the synthesis of FDCA through the 5-hydroxymethylfurfural(HMF)route in recent years.The connection and differ-ence between the HMF route and other routes were introduced,and the advantages of the HMF route were explained.The methods for synthesizing FDCA using HMF were introduced and analyzed in detail,including direct oxidation meth-od,precious metal catalysis method,transition metal catalysis method,photoelectric catalytic oxidation method,enzyme catalysis method,and whole cell biocatalysis method.In addition,based on the above-mentioned methods,the advantag-es and disadvantages of these methods were explained,and the challenges existing in the preparation of FDCA through the HMF route were discussed,including the selection,improvement and development of catalysts,optimization of reac-tion conditions,and treatment of intermediate products.The future prospects in the preparation of FDCA through the HMF route were also discussed.
