reaction mixtures. Here, we show that quantitative HMBC NMR can be applied to understand the complexity of the catalytic oxidation of glucose to glucaric acid, which is a promising bio-derived precursor to adipic acid, under aqueous aerobic conditions. It is shown through 2D NMR analysis that the product streams of this increasingly studied reaction contain lactone and dilactone derivatives of acid products
长期以来,定量相关的1 H– 13 C NMR是一种用于定量复杂反应混合物成分的潜在方法。在这里,我们表明定量HMBC NMR可以用于了解葡萄糖在水溶液中好氧条件下催化氧化为葡糖二酸的复杂性,葡糖二酸是己二酸的一种有前途的生物来源前体。通过2D NMR分析表明,这个日益研究的反应的产物流包含酸产物(包括葡糖二酸)的内酯和二内酯衍生物,而使用传统色谱技术无法观察/量化。葡萄糖转化率为98%时,总C 6内酯收率达到44%。此外,对催化剂稳定性的研究表明,所有的Pt催化剂都经历了产物介导的化学浸出。通过催化剂开发研究,表明可以通过使用碳载体来实现沥滤Pt的螯合。
