Solubilities of CO2 in aqueous N-methyldiethanolamine and guanidinium trifluoromethanesulfonate ionic liquid systems at elevated pressures
In this work, the solubility of CO2 in aqueous blended systems of N-methyldiethanolamine (MDEA) and guanidinium trifluoromethanesulfonate ([gua]+[OTf]−) have been carried out. The solubilities were measured at temperature 303.2 K, 323.2 K and 333.2 K, over CO2 partial pressure ranging from 500 to 30...
