Propuesta de la destilación extractiva con líquidos iónicos para la separación de hidrocarburos aromáticos de las gasolinas de pirólisis. El líquido iónico 1-ethyl3-methylimidazolium tricyanomethanide ([emim][TCM]) ha sido el que mejores resultados ha obtenido. This work proposes the use of the extractive distillation with ionic liquids (ILs) for the separation of aromatics from pyrolysis gasoline to overcome liquid-liquid extraction limitations. Among all the ILs proved so far, 1-ethyl3-methylimidazolium tricyanomethanide ([emim][TCM]) stands as the most promising in the extractive distillation of aromatics due to its high and compensate aromatic/aliphatic selectivities and aromatic distribution ratios, high thermal stability, and low viscosity. The separation of benzene, toluene, and xylene (BTX) from a pyrolysis gasoline model was experimentally investigated to check the real suitability of the [emim][TCM] for extractive distillation.
