Solubility of carbon dioxide in the ionic liquids, 1-butyl-1- methylpyrrolidinium trifluoromethanesulfonate and trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide

摘要

Solubilities of CO2 in IL's, 1-butyl-1-methylpyrrolidinium trifluoromethanesulfonate and trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide have been experimentally studied for develop- ment of a CO2 purification process. 1-butyl-1- methylpyrrolidinium trifluoromethanesulfonate and trihexyltetra-decylphosphonium. The ranges of temperature and pressure for experimental measurements are 313.15 K to 373.15 K and 3.5 bars to 108 bars, respectively.
