Abstract

The development of high efficient

economic and green SO

absorbers not only has a strong academic value

but also has a good application prospect. Herein

a series of ether-containing anion-functionalized ionic liquids were designed and prepared. The effect of ether on SO

absorption was investigated. The results indicated that SO

capacity increased significantly when ether was introduced on the anion. Furthermore

absorption capacity of SO

did not decrease obviously when the cation with a smaller molar mass tributyl ethyl phosphorus [P

4442

]

was used. The effective absorption capacity of [P

4442

]

[2-CH

OPhCOO

]

was 3.32 mol SO

per 1 mol IL at 20℃ and 10

with the effective mass absorption of 0.56 g SO

per 1 g IL. The cycles of six absorption and desorption showed that SO

capture by [P

4442

]

[2-CH

OPhCOO

]

was efficient and reversible. The method introducing ether to improve gas capture may be useful for other fields such as separation

catalyst and so on.
