Molar conductivities, Λ, of dil. solns. of the ionic liqs. 1-butyl-3-methylimidazolium chloride and 1-butyl-3-methylimidazolium tetrafluoroborate in methanol and DMSO were detd. as a function of temp. (methanol, T = (273.15 to 313.15) K; DMSO, T = (293.15 to 318.15) K). The data were analyzed with Barthel's low-concn. chem. model (lcCM) model to obtain the limiting molar conductivities, Λ∞(T), ...

Molar conductivities, Λ, of dil. solns. of the ionic liqs. 1-butyl-3-methylimidazolium chloride and 1-butyl-3-methylimidazolium tetrafluoroborate in methanol and DMSO were detd. as a function of temp. (methanol, T = (273.15 to 313.15) K; DMSO, T = (293.15 to 318.15) K). The data were analyzed with Barthel's low-concn. chem. model (lcCM) model to obtain the limiting molar conductivities, Λ∞(T), and assocn. consts., K°A(T), of these electrolytes. From Λ∞(T), the Eyring activation enthalpy of charge transport and (where possible) the ion cond. of the cation, λ∞([bmim]+), were detd.
