In a preferred embodiment, the preparation method of ionic liquid of the present invention includes the following steps:

1) N- methylimidazole is warming up to 40~50 DEG C, butane sultone reaction is added, and wash, dry, obtains centre Body A；

2) intermediate A and p-methyl benzenesulfonic acid are reacted at 110~130 DEG C, and is cooled to 90~100 DEG C, washed, it is dry Obtain the ionic liquid.

The present invention is reacted by N- methylimidazole (No. CAS: 616-47-7) and butane sultone (No. CAS: 1633-83-6) Generate the imidazoles inner salt containing sulfonate radical, react with p-methyl benzenesulfonic acid generate imidazoles acidic ion liquid, simultaneously contain nitrogen sun from The structure of son and p-methyl benzenesulfonic acid anion.

Suitable ionic liquid is added in a medicament in order to improve medicament to the infiltration rate of dust in applicant, find from The addition of sub- liquid can largely improve medicament to the absorption efficiency of dust, and to medicament by 50~60 DEG C from After heart filtering, moreover it is possible to continue to use to absorb the dust in polishing.This may be due in the ionic liquid in addition to containing N- The azonia center that sulphonic acid ester is formed in methylimidazole and butane is with except p-methyl benzenesulfonic acid anionic centers, and there is also acidity Sulfonic group, can act on forming the metal ions such as magnesium ion, aluminium ion with alkali metal components such as magnesium, aluminium in dust, and this It can be good at forming complex compound between a little groups such as metal ion and p-methyl benzenesulfonic acid anion, butane sulfonic group, by dust It cracking can absorb.Since the positive and negative charge center in the ionic liquid forms dissolution due to biggish steric effects The strong salt of ability, between positive and negative charge strong attraction and biggish steric effects cause its to the coordination ability of metal ion not By force, even if there are sulfonic groups will not form stable salt with metal ion, therefore power should the effects of higher temperature, centrifugal force Complexing power between ionic liquid and metal ion is broken, and is promoted other negative in the metal ion and system in medicament Ion forming salt, and precipitate under the action of the centrifugal force, thus the ability for making ionic liquid have absorption dust again.

Preferably, the molar ratio of N- methylimidazole and butane sultone is 1:(1~1.1 in step 1) of the present invention).

It is highly preferred that the molar ratio of N- methylimidazole and butane sultone is 1:1.05 in step 1) of the present invention.

It is further preferred that washing solution is ether in step 1) of the present invention.

It is further preferred that in step 1) of the present invention drying temperature be 80~90 DEG C, drying time be 1~ 1.3h。
