Abstract:
This article reviews the recent research progress of preparation of 2, 5-furandiformaldehyde(DFF) by the oxidation of 5-hydroxymethylfurfural(HMF) with transition metal-based catalysts. The application of manganese-based, copper-based, vanadium-based, iron/cobalt-based and other catalytic systems in the preparation of DFF by HMF oxidation is mainly introduced. The effects of different reaction conditions on the catalytic performance of the catalyst are analyzed in detail, the reaction mechanism of different catalysts is explained, and the advantages and disadvantages of different catalysts are summarized. In addition, based on the analysis of the existed problems in the current catalyst catalysis process, the development prospects of the transition metal-based catalysts catalyzed by HMF oxidation to prepare DFF are also prospected.
