Embodiment 1
[0014] Step 1: Add N-methylimidazole and n-butane bromide into a three-necked flask at a molar ratio of 1:1.05, stir magnetically at 110°C, condense and reflux for 1 hour, and obtain a light yellow viscous liquid [Bmim]Br. The liquid crude product was washed 3 times with ethyl acetate, distilled under reduced pressure, added acetone, oscillated to dissolve, added a small amount of seed crystals, allowed to stand for 2-3 hours, and [Bmim]Br was crystallized, and the acetone was separated by suction filtration to obtain high-purity The intermediate [Bmim]Br was dried in a vacuum oven at 70°C until constant weight.
[0015] The second step: the synthesis of basic ionic liquid [Bmim]oH, take an appropriate amount of ionic liquid intermediate [Bmim]Br dissolved in 50ml of dichloromethane, add equimolar granular solid sodium hydroxide, stir at room temperature for 10h , remove the NaBr precipitate by suction filtration, remove the solvent by rotary evaporation at 40°C, and obtain th...
Embodiment 2
[0017] [Emim][Ac] can be obtained by changing the brominated alkanes bromobutane to bromoethane, and other steps and conditions remain unchanged.
