摘要
为了制备高产率的2,5-呋喃二甲酸(FDCA),以纳米金属氧化物CuO和Co3O4为催化剂,次氯酸钠为氧化剂,在常温常压条件下催化氧化生物质基化合物5-羟甲基糠醛(5-HMF)合成2,5-呋喃二甲酸,并探讨得到了最佳反应条件。在最佳反应条件下制得目标产物2,5-呋喃二甲酸的总收率为98%。催化剂CuO和Co3O4表现出优异的催化性能,同时CuO的循环稳定性良好,循环5次后仍能保持较高的活性,表明CuO作为催化剂在该体系中具有广阔的前景。
In order to prepare 2,5-furandicarboxylic acid in high yield,nano metal oxides Cu O and Co3 O4 are used as catalysts,and sodium hypochlorite is used as an oxidant to catalyze the oxidation of the biomass-based compound 5-hydroxymethylfurfural under atmospheric pressure and room temperature conditions.The optimal reaction conditions are also explored and gained.The total yield of 2,5-furandicarboxylic acid reaches 98%under the optimum reaction conditions.Both Cu O and Co3 O4 show excellent catalytic performance.The circulation stability of Cu O is good and its activity remains relatively high after 5 cycles,indicating that Cu O as a catalyst has a broad prospect in the system.
