Specific conductance of the diluted solutions of 1-butyl-3-methylimidazolium bis(triluoromethy-lsulfonyl)imide, 1-butyl-3-methylimidazolium trifluoromethylsulfate (triflate) and 1-octyl-3-methylimidazolium triflate in acetonitrile have been measured on the temperature range 20 – 65 °C. By using conductometric data and Lee-Wheaton equation the thermodynamics parameters of association of the investigated ionic liquids have been calculated. It is established that with temperature increase the association of the investigated electrolytes in acetonitrile becomes stronger, whereas the energy of activation of conductivity remains invariable.
