现代化学的重点是通过使用可持续和经济的方法来满足消费者的需求。在氢氧化钠存在下，在一定的反应条件下，使用1%的AuPd/Mg(OH)(2)催化剂，可以将木质纤维生物质形成的平台化合物--呋喃甲醛选择性地氧化为呋喃甲酸，该催化剂对该反应表现出良好的重复使用性能。这种转化的机制是复杂的，可能有多条竞争途径。可以微调实验条件和AuPd金属比，以提供更好的反应选择性控制。用初始速率法计算了均相Cannizzaro反应和呋喃甲醛催化氧化反应的活化能。这项工作突出了使用一种具有商业应用潜力的多相催化剂将呋喃甲醛氧化为呋喃甲酸的潜力。
The emphasis of modern chemistry is to satisfy the needs of consumers by using methods that are sustainable and economical. Using a 1% AuPd/Mg(OH)(2) catalyst in the presence of NaOH and under specific reaction conditions furfural; a platform chemical formed from lignocellulosic biomass, can be selectively oxidised to furoic acid, and the catalyst displays promising reusability for this reaction. The mechanism of this conversion is complex with multiple competing pathways possible. The experimental conditions and AuPd metal ratio can be fine-tuned to provide enhanced control of the reaction selectivity. Activation energies were derived for the homogeneous Cannizzaro pathway and the catalytic oxidation of furfural using the initial rates methodology. This work highlights the potential of using a heterogeneous catalyst for the oxidation of furfural to furoic acid that has potential for commercial application.
