功能化离子液体-MDEA复配体系吸收CO2
Absorption of CO2 in aqueous mixtures of functionalized ionic liquids and MDEA
摘要
Abstract
Two functionalized ionic liquids (ILs) - tetraethylammonium alaninate ([N2222][Ala]) and tetraethylammonium serinate ([N2222][Ser]) were synthesized by using the one-step method and verified with IR and 1H NMR, and their glass transition temperature and thermal decomposition temperature were determined. The solubility of CO2 in aqueous blends of N-methyl-diethanolamine (MDEA) and these two ILs were carried out at 40 ℃ and the results showed that both of these two ILs had a positive effect on the absorption of CO2, increasing by 8.63% and 5.40%, respectively, when IL's concentration was 10%. Moreover, physical properties namely, density and viscosity of these mixed solutions were measured over a temperature range of 20℃ to 60 ℃ to provide basic data for further application of ILs.关键词
