The density and surface tension of the ionic liquid (IL) [C(2)mim][B(CN)(4)] (1-ethyl-3-methylimidazolium tetracyanoborate) were measured in a temperature range from (283.15 to 338.15) K. In terms of Glasser's semiempirical relation of ILs, the standard molar entropy and the lattice energy of the homologous series of ILs [C(n)mim][B(CN)(4)] were estimated, respectively. Using Kabo's method and Rebelo's method, the molar enthalpy of vaporization of [C(2)mim][B(CN)(4)], Delta H-g(I)m(0) (298 K), at 298 K, and Delta H-g(I)m(0) (T-b), at hypothetical normal boiling point, T-b = 680 K, was estimated, respectively. According to the interstice model, the thermal expansion coefficient of [C(2)mim][B(CN)(4)], alpha = 4.77.10(-4) K-1, was estimated and was in good agreement with experimental value.
