摘要
用最大气泡法和韦氏天平法,在278.15~343.15K范围内测定了离子液体BMIBF4的表面张力和密度;讨论了这个离子液体的体积性质和表面性质;根据离子个头大又极不对称的特点,提出了离子液体的空隙模型.根据空隙模型计算的离子液体恒压热膨胀系数与实验值相比,偏差在10%左右.
This paper reported the densities, and surface tension of the pure ionic liquid BMIBF4 under dry argon in the temperature range of 278.15 to (343.15 +/- 0.1) K. The volumetric properties and the properties of surface for ionic liquid were discussed. The interstice theory was put forward and the thermal expansion coefficient, a, calculated by the theory was in good agreement with experimental value.
