【Abstract】 The electrical conductivity and density of binary mixtures formed from 1-n-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) and different molecular liquids were measured at 25°C, and the molar conductivity of the ionic liquid (IL) was calculated. The results showed that the molar conductivity of the IL increased dramatically with the concentration of the molecular liquids. It was discovered that the molar conductivity of the IL (∧m) can be well correlated by the molar conductivity of the neat IL (∧I ) and the dielectric constants (ε) of the molecular liquids, and the equation can be expressed as following. ∧m = =∧I exp (xs/a) (1) a = 2.89 - 0.0125ε – 0.558lnVm where ε and Vm stand for dielectric constant and molar volume of the molecular liquids, respectively.更多还原
