Research on the Dissolution of Glucose in Imidazolium-based Ionic Liquids

不同温度下,系统测定了葡萄糖在离子液体1-丁基-3-甲基咪唑四氟硼酸盐和1-丁基-3-甲基咪唑六氟磷酸盐中的溶解度。根据实验结果和理论公式,计算得到了溶解反应的主要热力学函数值。研究表明,1-丁基-3-甲基咪唑四氟硼酸盐对葡萄糖的溶解能力更强。葡萄糖在离子液体中的溶解是典型的吸热过程,受温度和溶解焓影响显著。

The solubility of glucose in ionic liquids 1-butyl-3-methylimidazolium tetrafluoroborate and 1-butyl-3-methylimidazolium hexafluorophosphate was measured at different temperatures.According to the experimental results and theoretical equations,the values of thermodynamic parameters were calculated.It shows that 1-butyl-3-methylimidazolium tetrafluoroborate has superior dissolving capability of glucose.The dissolution of glucose in ionic liquids is a typical endothermic process,which is significantly influenced by temperature and solution enthalpy.
