| 摘 要： | 在活性炭负载金属钌(Ru/C)催化剂上实现了5-羟甲基糠醛的高效选择氧化.以甲苯为反应溶剂,在383 K和2.0 MPa O2的反应条件下,2,5-呋喃二甲醛(DFF)收率高达95.8%.与活性炭负载的具有相似粒径的Pt,Rh,Pd,Au等其它贵金属催化剂相比,Ru/C具有更加优良的活性和DFF选择性.同时Ru/C催化剂结构稳定,具有良好的重复使用性能.在相似的反应条件下,采用水代替甲苯作为溶剂,同时添加少量水滑石固体碱,可便捷地将主要产物从DFF调变为5-甲酰基-2-呋喃甲酸或2,5-呋喃二甲酸,显示出Ru/C催化剂在控制5-羟甲基糠醛选择氧化反应产物方面的优异性能.

| Abstract: | The aerobic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) was per-formed on an activated carbon-supported ruthenium (Ru/C) catalyst. The excellent DFF yield of 95.8% was achieved at 383 K and O2 pressure 2.0 MPa in toluene. It exhibited superior activity and DFF selectivity than other C-supported noble metals (i.e. Pt, Rh, Pd, and Au) with comparable nanoparticle size. The Ru/C catalyst was stable and can be recycled by a simple hydrothermal treatment. Moreover, the product distribution in the HMF oxidation on Ru/C can be tuned by the use of water as solvent and the addition of hydrotalcite, giving either 5-formyl-2-furancarboxylic acid or 2,5-furandicarboxylic acid as the dominant product. |
