| 摘 要： | 在293.15~343.15 K温度范围内，用MYX-1密度计测定了系列离子液体 1-丁基-3-甲基咪唑硫酸氢盐C4mim]HSO4 (1-butyl-3-methylimdazolium hydrosulfate)、1-己基-3-甲基咪唑硫酸氢盐C6mim]HSO4 (1-hexyl-3-methylimdazolium hydrosulfate)、1-辛基-3-甲基咪唑硫酸氢盐C8mim]HSO4 (1-octyl-3-methylimdazolium hydrosulfate)、1-癸基-3-甲基咪唑硫酸氢盐C10mim]HSO4 (1-decyl-3-methylimdazolium hydrosulfate)的密度。利用不同温度下的密度值计算得出了离子液体的热膨胀系数及分子体积。利用Glasser经验方程计算了离子液体的标准熵和晶格能，并进一步对其热力学性质进行了讨论。
