          Abstract

          El interés de los científicos por los líquidos iónicos ha ido creciendo en los últimos años, demostrado con el gran número de publicaciones y patentes sobre líquidos iónicos. Dadas las ventajas que presentan como disolventes alternativos a los disolventes moleculares, en la separación de las mezclas etanol-agua, en este trabajo se presentan las principales características, propiedades y aplicaciones de estos compuestos. Además se muestran los resultados obtenidos en la separación de las mezclas etanol-agua, con varios líquidos iónicos que han sido empleados. Finalmente se resaltan las principales ventajas que presentan los líquidos iónicos frente a los solventes convencionales, en la separación de la mezcla etanol-agua.

          Translated abstract

          The interest of scientists for ionic liquids has been growing up in recent years, which has been demonstrated by the large number of publications and patents on ionic liquids. Due to the advantages presented by them as an alternative to molecular solvents in the separation of ethanol-water mixtures, in this paper we present the main characteristics, properties and applications of these compounds. Furthermore, the results of the separation of the ethanol-water mixtures, with various ionic liquids used are displayed. Finally, the main advantages of ionic liquids compared to conventional solvents in the separation of the ethanol-water mixture are highlighted.

          Applications of ionic liquids in the chemical industry.

          In contrast to a recently expressed, and widely cited, view that "Ionic liquids are starting to leave academic labs and find their way into a wide variety of industrial applications", we demonstrate in this critical review that there have been parallel and collaborative exchanges between academic research and industrial developments since the materials were first reported in 1914 (148 references).
