Synthesis and physicochemical properties of N-decylpyridinium salts with inorganic anions

Resumo

Ionic liquids with N-decylpyridinium cation and inorganic anions SO₄^2–, NO₃^–, SCN^–, NO₂^–, BF₄^– were synthesized. The structure and composition of the synthesized compounds was proved by elemental analysis and IR spectroscopy. Electroconductivity of aqueous solutions of new ionic liquids was studied, critical concentrations of micelle formation was determined, and thermal stability in air in the temperature range 25–500°С was investigated.
