This paper represents the material conductivity investigation of several AILs (Acidic Ionic Liquids) containing an alkane sulfonic acid group covalently bonded to pyridine and Nalkylimidazole cations. Three different anions (HSO 4 -, H 2 PO 4 and TsO -) have been introduced in the structure of ionic liquids to evaluate the impact of this factor on material conductivity. Ion conductivity values in all studied ionic liquids obtained from impedance measurements in temperature range from 20 to 120 o C. Values of electroconductivity depending on ionic liquid's structure vary in rage from 1.34•10 -5 to 1.05•10 -2 S/cm at 25 o C.
