Liquid-Liquid Equilibria in Systems 1-Ethyl-3-methyl-imidazolium Ethylsulfate + C7-Hydrocarbons
Original language description
Liquid-liquid equilibrium was determined in three binary systems of 1-ethyl-3-methylimidazolium ethylsulfate (abbr. [emim][C5H2SO4]) towards aliphatic, cyclic and aromatic hydrocarbons. Our measurements show that the highest values of mutual solubilitiesappear in the system [emim][C5H2SO4] + toluene. The present data were correlated along with literature values by the modified Flory-Huggins equation proposed by de Sousa and Rebelo, and by the molecular-thermodynamic lattice model proposed by Qin and Prausnitz. Both models describe experimental data in the measured systems very well. Good agreement of our data with available literature values was confirmed with an exception of the system of [emim][C5H2SO4] + toluene in which partial discrepancies of our data with those by Meidersma et al. were found.
