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, α, calculated by the theory was in good agreement with experimental value.

Key words: ionic liquid, density, surface tension, interstice theory, BMIBF4
