摘　　要：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 Al2O3 as 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.
