摘要: The effect on gas solubilities of adding partially fluorinated alkyl side chains either imidazolium-based cations or bis(perfluoroalkylsulfonyl)amide anions was studied. aim to gain knowledge the mechanisms dissolution gases in ionic liquids and, if possible, improve physical absorption carbon dioxide liquids. We have determined experimentally, temperature range 298–343 K and at pressures close atmospheric pressure, solubility thermodynamics solvation dioxide, ethane, nitrogen 1-octyl-3-methylimidazolium bis[trifluoromethylsulfonyl]amide ([C8mim][NTf2]), bis[pentafluoroethylsulfonyl]amide ([C8mim][BETI]), 1-(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)-3-methylimidazolium ([C8H4F13mim][NTf2]), ([C8H4F13mim][BETI]).
