摘要
For the purpose of developing advanced new absorbents for carbon dioxide, ionic liquids (ILs) are considered as alternative materials due to their superior properties to conventional organic solvents. Since low CO2 solubility in ionic liquids is a major concern for their application as absorbents, it is essential to focus on improving CO2 absorbing capability of ILs. In this paper, strongly basic ionic liquids, namely [C-n-mim]OPh (n = 2, 4, 6), have been synthesized and studied over a wide range of temperature and pressure changes. [Cn-mim]OPh can be easily synthesized from corresponding [C-n-mim]Cl and sodium phenoxide and has been found to be good CO2 absorbents.
