1,3-二磺酸根咪唑四氯化铝盐{[Dsim]AlCl4}作为一种新型的磺酸根咪唑盐，同时具有布朗斯特酸和路易斯酸性质。本文合成了1,3-二磺酸根咪唑四氯化铝盐，并将其用于催化葡萄糖转化为5-羟甲基糠醛（5-HMF）的反应。研究表明：反应温度、反应时间和催化剂用量对催化葡萄糖转化为5-HMF这一反应起着重要的影响，提高反应温度能够缩短反应时间，进一步延长反应时间，5-HMF的产率反而减少。在最优化的条件下（140℃，30 min），5-HMF的产率可达52.1%。此外，动力学分析揭示了{[Dsim]AlCl4}在DMSO中催化葡萄糖转化为5-HMF的反应为二级反应，并计算出其活化能为138 kJ·mol-1。本研究对咪唑金属盐催化转化葡萄糖制备5-HMF具有一定的指导意义。

1,3-Disulfonic acid imidazolium tetrachloroaluminate {[Dsim]AlCl4} is a novel analogue of sulfonic acid functionalized imidazolium salts (SAFIS) with Bronsted acidic and Lewis acidic properties. In this work, 1,3-Disulfonic acid imidazolium tetrachloroaluminate is synthesized, and catalyzes the conversion of glucose into 5-hydroxymethyl furfural (5-HMF). The reaction temperature, reaction time and catalyst amount play key roles in the conversion of glucose into 5-HMF. Increasing the reaction temperature can shorten the reaction time. Further extending the reaction time, the yield of 5-HMF will decrease. A 5-HMF yield of 52.1%can be achieved under an optimum condition (140oC, 30 min). In addition, kinetic analysis reveals that the reaction is second ordered and the activation energy is 138 kJ·mol-1. This study is instructive for the conversion of glucose into 5-HMF using imidazolium salts.
