以葡萄糖为原料、强酸性阳离子交换树脂732和Al₂O₃为催化剂、二甲基亚砜（DMSO）为反应介质,研究了5-羟甲基糠醛（5-HMF）的制备方法与反应过程,以及阳离子树脂732和Al₂O₃的重复使用性.结果表明,DMSO对葡萄糖转化为5-HMF的反应有促进作用,葡萄糖初始质量分数为10%时,130℃下反应12 h后,葡萄糖的转化率可达90.19%,5-HMF的得率可达44.53%,选择性可达49.37%.同时,文中研究结果显示,经过多次使用,阳离子树脂732和Al₂O₃的催化选择性依然保持稳定.

5-Hydroxymethylfurfural（5-HMF） was prepared from glucose,with strong-acid cation exchange resin 732 and Al₂O₃as the catalysts and with DMSO as the reaction medium.Then,the corresponding reaction process was investigated,and the stabilities of both the resin and Al₂O₃ were analyzed.The results show that DMSO accele-rates the catalytic conversion of glucose,that the glucose conversion,the 5-HMF yield and the selectivity respectively reach 90.19%,44.53% and 49.37% after a 12-h reaction at 130 ℃ with an initial glucose content（mass fraction） of 10%,and that resin 732 and Al₂O₃ keep stable even after being used for many times.
