Solubility of CO2 and CH4 in sterically hindered amine-based deep eutectic solvents

Decarbonization of methane is essential in many applications such as biogas and natural gas. Solvents with high selectivity towards CO2 are required for the upgradation of biogas and natural gas. Deep eutectic solvents (DESs) sharing green properties of ionic liquids have shown the ability to capture CO2 selectively. In this work, we have synthesized four novel secondary amine-based DESs using quaternary ammonium salt as hydrogen bond acceptor....
