摘要: 采用廉价催化剂硅酸铝盐与痕量的盐酸组合,在双相体系中催化碳水化合物有效地转化制备5-羟甲基糠醛(HMF)。葡萄糖在水/正丁醇两相体系中在453 K下反应30min达到了100%的转化率,并可以获得61.5%产率的HMF。同时,在双相体系中在453 K下反应40min能有效地转化多糖(蔗糖、麦芽糖、淀粉和纤维素)制备HMF。此外,硅酸铝盐可以多次重复使用,试验中重复5次以上其活性没有明显下降。本催化体系在碳水化合物转化制备生物燃料和化学品领域具有很好的成本效益和商业应用潜力。

Abstract: Cheap catalyst aluminum silicate was combined with HCl to efficiently convert carbohydrates to 5-hydroxymethylfurfural (HMF) in a biphasic system. Glucose can yield 61.5% of 5-HMF in an H2O/n-butanol biphasic system at 453 K within 30 min. Polysaccharides (sucrose, maltose, starch and cellulose) can also be converted to HMF effectively in this biphaisc system at 453 K for 40 min. In addition, aluminum silicate can be reused over five cycles without a significant decrease in its activity. Such catalytic system has the potential to become an effecient and cost-effective approach to the conversion of carbohydrates into bio-fuels and platform chemicals.
