We present a study on the phase equilibrium behaviour of binary mixtures containing two 1-alkyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imide-based ionic liquids, [Cnmim][NTf2] (n = 2 and 4), mixed with diethylamine or triethylamine as a function of temperature and composition using different experimental techniques. Their phase behaviours have been then correlated and predicted by using Flory-Huggins equations and UNIQUAC method. The potential of the COSMO-RS methodology to predict the phase equilibria was also tested for the studied binary systems. The liquid state structure of the binary mixture [C2mim][NTf2] + diethylamine has also been investigated by molecular dynamics simulation and neutron diffraction. Finally, the absorption of gaseous ethane by the ([C2mim][NTf2] + diethylamine) binary mixture was determined and compared with those observed in the pure solvents.
