- Аннотация: Ionic liquid N-methyl-N-(2-(2-methoxyethoxy)-ethyl)-morpholinium bis-(trifluoromethylsulfonyl) imide was synthesized for the first time by nucleophilic substitution of bromide ion by N-methyl-morpholine. The composition was confirmed by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy. Using thermal analysis and mass spectroscopy, thermal stability of this ionic liquid as well as possible directions of its destruction was analyzed. Melting point for this liquid using differential scanning calorimetry (DSC) was estimated in the range (−80 to −74) °C. The dependence of electroconductivity of acetonitrile solution on concentration and temperature was studied for dissociation constant and conductivity activation energy calculations, respectively. The electrochemical stability window for this ionic liquid was defined by cyclic voltammetry and estimated as 4.84 V.
