Examples
Embodiment 1
[0015] Embodiment one: N, N, N trimethyl-N-butyl bisulfate ([N1114]HSO 4 )synthesis
[0016] (1) Add 0.1 mol trimethylamine aqueous solution to a single-necked flask, then add 0.1 mol dibutyl sulfate, heat and stir in a 50°C water bath for about 12 hours after the addition, to obtain a colorless transparent ionic liquid aqueous solution.
[0017] (2) Dissolve the above liquid and 0.15mol KOH in ethanol respectively, then mix the two solutions, remove the resulting white precipitate, and collect the filtrate to obtain a colorless liquid.
[0018] (3) Add 0.15 moles of H to the solution 2 SO 4 , stirred evenly to obtain a colorless transparent liquid. The liquid was evaporated in a rotary evaporator to remove most of the water, ethanol and acetic acid produced to obtain a light yellow viscous liquid, which was dried in vacuum to obtain a viscous light yellow liquid, which was the product.
Embodiment 2
[0019] Embodiment two: N, N, N trimethyl-N-propyl bisulfate ([N1113]HSO 4 )synthesis
[0020] (1) Add 0.1 mol trimethylamine aqueous solution to a single-necked flask, then add 0.1 mol dipropyl sulfate, heat and stir in a 50°C water bath for about 12 hours after the addition, to obtain a colorless transparent ionic liquid aqueous solution.
[0021] (2) Dissolve the above liquid and 0.15mol KOH in ethanol respectively, then mix the two solutions, remove the resulting white precipitate, and collect the filtrate to obtain a colorless liquid.
[0022] (3) Add 0.15 moles of H to the solution 2 SO 4 , stirred evenly to obtain a colorless transparent liquid. The liquid was evaporated in a rotary evaporator to remove most of the water, ethanol and acetic acid produced to obtain a light yellow viscous liquid, which was dried in vacuum to obtain a viscous light yellow liquid, which was the product.
Embodiment 3
[0023] Embodiment three: N, N, N trimethyl-N-ethyl bisulfate ([N1112]HSO 4 )synthesis
[0024] (1) Add 0.1 mol trimethylamine aqueous solution to a single-necked flask, then add 0.1 mol diethyl sulfate, heat and stir in a 50°C water bath for about 12 hours after the addition, to obtain a colorless transparent ionic liquid aqueous solution.
[0025] (2) Dissolve the above liquid and 0.15mol KOH in ethanol respectively, then mix the two solutions, remove the resulting white precipitate, and collect the filtrate to obtain a colorless liquid.
[0026] (3) Add 0.15 moles of H to the solution 2 SO 4, stirred evenly to obtain a colorless transparent liquid. Evaporate the liquid in a rotary evaporator to remove most of the water ethanol and the acetic acid produced to obtain a light yellow viscous liquid, dry it in vacuum and wash with ethanol to obtain a white solid, which is the product. Although this ionic liquid is not suitable as a PEMFC An electrolyte, but also a salt that c...
