摘要：

We present for the first time the determination of molar conductances, Lambda, of ionic liquids solutions (ILs) such as 1-ethyl-3-methylimidazolium tetrafluoroborate [emim][BF4] and 1-butyl-3methylimidazolium tetrafluoroborate [bmim][BF4] as a function of temperature. The data was analyzed with Barthel's lcCM model to obtain ionic association constants, K-A, limiting molar conductances, Lambda(o) of these electrolytes. The examined ionic liquids are practically fully dissociated in water over the whole temperature range (283.15 to 318.15 K). From the temperature dependence of the limiting molar conductivities the Eyring's activation enthalpy of charge transport was determined. The Walden product values were also calculated.
