功能型离子液体的合成表征及CO2吸收性能
Synthesis and identification of functional ionic liquids and research on its performance of CO2 absorption
摘要
Abstract
Two kinds of traditional ionic liquids ( [bmim]BF4, [emim]BF4) and three kinds of functional ionic liquids containing amino group and hydroxy group ( [NH2P-mim]Br, [NH2-e-mim]BF4, [OH-e-mim]Br) were synthesized. IR,1H NMR were used to determine the structures and properties of these ionic liquids. CO2 adsorptive experiments were made in a laboratory bench-scale system with the ionic liquids at atmosphere pressure and room temperature to determine the parameters of the CO2 saturated adsorption and its adsorptive balance time. Comparing the differences of CO2 adsorptive performance with the functional and traditional ionic liquids, it was found that CO2 saturated adsorption capabilities of the functional ionic liquids with amino group ( [NH2P-mim]Br, [NH2-e-mim]BF4) and hydroxyl group ( [OH-e-mim]Br) were 3-9 times and 1-2 times greater than the unmodified ionic liquid respectively, the functional ionic liquids containing ethyl functional groups always had shorter adsorption balance time. Finally, the influence of the temperature and CO2 partial pressure on the process of functional ionic liquid adsorption of CO2 was discussed.关键词
