| 摘 要： | 运用核磁共振手段, 研究了室温离子液体1-辛基-3-甲基咪唑四氟硼酸盐(C8mim]BF4])在不同比例的离子液体／丙酮混合体系中1H和13C的化学位移及13C的自旋-晶格弛豫时间(T1). 结果表明, 离子液体C8mim]BF4]的阳离子芳环上的氢原子, 以及与氮原子直接相连的甲基和亚甲基上的氢原子都与丙酮羰基上的氧原子有相互作用, 从而减弱了离子液体阴阳离子间的强相互作用, 使离子液体的运动加快, 黏度降低.

| Abstract: | 1H NMR, 13C NMR, and 13C spin-lattice relaxation time(T1) of the mixtures of room temperature ionic liquid C8mim]BF4] and acetone with different proportions have been studied by NMR. The results indicated that the interaction between the protons of the ring, the methyl and methylene next to the nitrogen of ionic liquids and the carbonyl oxygen of acetone weakened the strong interaction between the cation and anion of the ionic liquid, thus increased the motion and decreased the viscosity of the ionic liquid. |
