Vanadium phosphate oxide (VPO) heterogeneous catalysts with different V/P molar ratios were prepared and used for selective oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) to produce 2,5-diformylfuran (DFF) in the liquid phase. It was found that the VPO catalyst with V/P molar ratio 0.25 exhibited the best catalytic performance. Then the VPO catalyst was utilized to catalyze the oxidation of HMF in a batch reactor under different conditions, in terms of type of solvent (water and organic), reaction time and temperature. A high DFF yield of 83.6% with HMF conversion of 100% was obtained under atmospheric pressure.
制备了具有不同钒/磷摩尔比的磷酸钒氧化物（VPO）多相催化剂，并将其用于生物质衍生的5-羟甲基糠醛（HMF）在液相中选择性氧化制备2,5-二糠醛（DFF）。结果发现，钒/磷摩尔比为0.25的VPO催化剂表现出最佳的催化性能。然后，在间歇式反应器中，在不同条件下，就溶剂类型（水和有机溶剂）、反应时间和温度而言，利用VPO催化剂催化HMF的氧化反应。在常压下获得了83.6%的高DFF产率，HMF转化率为100%。
