Sažetak
Molar conductivity of diluted solutions of ionic liquid of 1-methyl-3-octylimidazolium chloride in formamide and N, N-dimethylformamide, was determined at eight temperatures in the region from 278.15 to 313.15 K, and in the concentration range from 0.0002 to 0.02 mol dm–3. The values of limiting molar conductivity, and association constant were calculated using the low concentration Chemical Model (lcCM) for investigated systems. From the limiting molar conductivity dependencies on temperature, the Eyring activation enthalpy values of the charge transfer were determined. Thermodynamic parameters such as Gibbs free energy, entropy, and enthalpy of ion association were estimated from the values of association constants at various temperatures. All quantities obtained in this work are reported and discussed, together with the Walden product in terms of the ionic size as well as solvent basicity, structure and permittivity.
