摘要：
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. © All Right Reserved.
