摘要

合成了一系列肉桂酸型功能化离子液体

研究了其CO2 吸收性能。结果表明

肉桂酸型功能化离子液体吸收二氧化碳性能良好

其阴离子苯环上的取代基会影响CO2 吸收性能。随着温度的升高和压力的降低

其CO2吸收性能都会降低。同时

该离子液体具有很好的循环稳定性

经过5 次吸收脱附循环

该离子液体仍能保持较高的CO2 吸收量。结合红外光谱和其低浓度下CO2 的吸收研究发现肉桂酸型离子液体吸收CO2 存在着化学作用。

Abstract

A series of cinnamic acid-based ionic liquids [P66614][CIN] were prepared and applied in the CO2 absorption. The results showed that the cinnamic acid-based ionic liquids exhibited good CO2 absorption performance. The CO2 absorption ability was influenced by the substituent in the cinnamic acid. The CO2 absorption capacity would decrease with increasing temperature or decreasing pressure. Furthermore

these ionic liquids exhibited excellent reversibility since higher CO2 absorption capacity can be maintained after 5 times of absorption/desorption circulation. The results of a combination of FT-IR spectrum and CO2 absorption under 10% CO2 indicated that CO2 was absorbed by chemisorption.
