Embodiment 1
[0036] The preparation of a class of ionic liquids
Embodiment 1-1
[0038] Under the protection of dry nitrogen, 0.065 mol (3.84 g) of acetamide was slowly added to 0.1 mol (13.34 g) of AlCl 3 , stirred at room temperature for 30 minutes, then heated up to 80° C., and continued to stir for 2 hours to complete the reaction to obtain an ionic liquid.
Embodiment 1-2
[0040] Under the protection of dry nitrogen, 0.055 mol (4.02 g) of N-methylacetamide was slowly added to 0.1 mol (13.34 g) of AlCl 3 , stirred at room temperature for 30 minutes, then heated up to 60° C., and continued to stir for 3 hours to complete the reaction to obtain a basic ionic liquid. Subsequently, under the protection of dry nitrogen, 0.015 mol (1.48 g) of CuCl was added to the basic ionic liquid and the temperature was raised to 120° C., and the stirring was continued to complete the reaction (completely converted into a liquid), and the ionic liquid was obtained.
