摘　　要：2,5-Furandicarboxylic acid（2,5-FDCA） has been regarded as the ideal bio-based alternative to terephthalic acid（TPA）. In recent years, great efforts have been made to synthesize 2,5-FDCA through the following methods：（1） oxidation of 5-hydroxymethylfurfural（HMF） in the presence of complex biocatalyst or metallic catalyst;（2） conversion of 2-furoic acid via the well-known Henkel Reaction. Herein, a new strategy for the synthesis of 2,5-FDCA from furan and acetic anhydride under mild condition is reported. The purity of the resulted 2,5-FDCA was above 99.9%. Acetic acid and iodoform generated in the reaction were recyclable and no other harmful by-products were detected. The thus-obtained 2,5-FDCA was applied for the preparation of poly（ethylene furandicarboxylate）（PEF） of high quality in terms of high molecular weight and good appearance.2,5-Furandicarboxylic acid（2,5-FDCA） has been regarded as the ideal bio-based alternative to terephthalic acid（TPA）.
