Abstract: | Ionic liquids with 1-butyl-3-alkylimidazolium (alkyl = C4H9, C8H17, or C10H21) cation and Br–, BF 4 – , or PF 6 – anions have been obtained. Composition and structure of the compounds have been confirmed by elemental analysis and IR spectroscopy data. Electrical conductivity of solutions of the synthesized compounds in acetonitrile has been studied, and association constant as well as equivalent electrical conductivity at infinite dilution have been calculated. Thermal stability of the prepared ionic liquids in air at 25–500°С has been studied. |
