This work studied the application of sulfonated ZSM-5 zeolite, a bi-functional catalyst for conversion of biomass-derived glucose to HMF. Glucose hydrolysate was obtained by enzymatic hydrolysis of rice straw, that was pretreated by sodium hydroxide. Glucose hydrolysate was then subjected to a transformation reaction to achieve HMF using HSO-ZSM-5 zeolite under the assistance of sonication. The reaction conditions including solvent, temperature, catalyst dosage and reaction time were studied. Suitable conditions, which gave the highest yield of HMF of 54.1% have been found. The HSO-ZSM-5 zeolite presented a high catalytic efficiency for conversion of glucose to HMF, an important and useful intermediate in the chemical industry.
本研究考察了磺化ZSM-5沸石作为一种双功能催化剂在将生物质衍生葡萄糖转化为HMF中的应用。葡萄糖水解产物通过对经氢氧化钠预处理的稻草进行酶水解获得。然后，在超声辅助下，使用HSO-ZSM-5沸石对葡萄糖水解产物进行转化反应以制备HMF。研究了包括溶剂、温度、催化剂用量和反应时间在内的反应条件。已发现能给出最高HMF产率54.1%的合适条件。HSO-ZSM-5沸石对将葡萄糖转化为HMF表现出高催化效率，HMF是化学工业中一种重要且有用的中间体。
