Abstract

The ionic conductivity, relative viscosity, and solution enthalpy of LiNTF2 and NaNTF2 solutions in ionic liquid BMINTF 2 have been measured. We observed that the conductivity decreased and the viscosity increased when the Li+ and Na+ salts were dissolved in BMINTF2. We also observed that the dissolution is an exothermic process with a solution enthalpy of approximately -18.07 ± 4.61 kJ/mol. The experimental results indicate that the Li+ ion may associate with multiple NTF2- anions in the BMINTF 2 solution to form a solvated complex.
