摘要
在273.2~353.2 K范围内,精确测定了[BMIM]HSO4离子液体的密度和表面张力。根据Glasser理论,讨论了该离子液体的热力学性质,估算出其晶格能和标准熵。根据离子液体的空隙模型计算了离子液体的恒压热膨胀系数α=7.8×10-4K-1,与实验值α=10.8×10-4K-1基本一致。
The density and surface tension of pure ionic liquid ]ClO4(1-butyl-3-methylimidazolium hydrosulfate) were measured in the temperature range of 293.2-353.2 K.Based on the Glasser’s theory,the thermodynamic property of the ionic liquid was investigated,such as the standard molar entropy and lattice energy.The thermal expansion coefficient,α= 7.8 × 10-4 K-1,calculated by the interstice model was in good agreement with α(experimental) = 10.8 × 10-4 K-1.
