Abstract

Ionic liquids exhibit, in general, a very interesting set of properties for their use as solvents. In particular, they look promising in the development of improved liquid-liquid extraction processes. This presentation will show results on the use of several ionic liquids for diverse applications by solvent extraction: concentration of essential oils of plants, separation of aromatic and aliphatic hydrocarbons, desulfurisation of fuels, and removal of metals from petroleum. These separation problems have been modelled by means of ternary systems, and the liquid-liquid equilibrium data for these systems have been determined. The results allow for an analysis of the suitability of the ionic liquids as extracting solvents in the applications suggested. Since several ionic liquids have been tried, an initial identification of desirable ions or structural features in the ionic liquid can also be made, in order to optimise the choice for a practical separation process.
