title: Surface tension of pure and water-containing ionic liquid C5MIBF4 (1-methyl-3-pentylimidazolium tetrafluoroborate).
abstract: The surface tension of ionic liquid (IL) C(5)MIBF(4) (1-methyl-3-pentylimidazolium tetrafluoroborate) with various amount of water was measured by the forced bubble method at 278.15 to 338.15+/-0.05 K. In terms of standard addition method, the surface tension of pure IL C(5)MIBF(4) was obtained. The properties of surface for pure C(5)MIBF(4) were discussed in terms of the principle of independent surface action and Glasser's theory of lattice energy. Using the surface tension data, the interstice model was examined.
