preparation example Construction
[0029] The embodiment of the present invention also provides a method for preparing an acidic polymeric ionic liquid, comprising the following steps:
[0030] Add the monomer, cross-linking agent, initiator and the first organic solvent into the reactor, stir and mix for 2-5 hours, react at 100-200°C for 24-48 hours, cool and dry to obtain the polymerized ionic liquid carrier, wherein , the polymerized ionic liquid monomer is an aromatic heterocyclic olefin, the addition amount of the initiator is 0.3% to 5% of the molar weight of the polymerized ionic liquid monomer, and the added amount of the crosslinking agent is 0.2% of the molar weight of the polymerized ionic liquid monomer. ~5 times, the addition amount of solvent is 5~25 times of the molar weight of polymerized ionic liquid monomer;
[0031] The polymeric ionic liquid carrier and the quaternary amination reagent are dissolved in a second organic solvent at a molar ratio of 1:0.5 to 1:1.5, and the amount of the second ...

[0038] Polymerized ionic liquid carrier was synthesized with ethyl acetate as solvent, ammonium persulfate as initiator, divinylbenzene as crosslinking agent and vinylimidazole as monomer. Synthetic process: Add divinylbenzene and 1-vinylimidazole to ethyl acetate at a molar ratio of 1:1, stir and mix in a constant temperature water bath for 2 hours. Then the above mixture was heat-treated with high-pressure solvent in an oven at 100°C for 24 hours, and dried in a vacuum oven at 80°C for 48 hours to obtain the polymerized ionic liquid.
[0039] Add the prepared polymeric ionic liquid to methyl iodide at a molar ratio of 1:1 into absolute ethanol, and stir at room temperature and pressure for 24 hours under dark conditions. After the reaction, filter, wash with ethyl acetate, and dry in a vacuum oven at 80° C. for 48 hours to obtain a quaternized polymeric ionic liquid.

[0042] Polymerized ionic liquid carriers were synthesized with ethyl acetate as solvent, ammonium persulfate as initiator, divinylbenzene as crosslinking agent and vinylpyridine as monomer. Synthetic process: Add divinylbenzene and 1-vinylimidazole to ethyl acetate at a molar ratio of 1:1, stir and mix in a constant temperature water bath for 2 hours. Then the above mixture was heat-treated with high-pressure solvent in an oven at 100°C for 24 hours, and dried in a vacuum oven at 80°C for 48 hours to obtain the polymerized ionic liquid.
[0043] Add the prepared polymeric ionic liquid to methyl iodide at a molar ratio of 1:1 into absolute ethanol, and stir at room temperature and pressure for 24 hours under dark conditions. After the reaction, filter, wash with ethyl acetate, and dry in a vacuum oven at 80° C. for 48 hours to obtain a quaternized polymeric ionic liquid.
