Ionic liquids (IL) remain hot topic in research community since 1990-es. By now, there are over 70 000 scientific articles published on this topic, describing both properties and applications of IL-s.
There are quite a few applications that have been commercialized already, and some of them are now in the pilot plant phase.
Many applications make use of unique combination of properties of IL-s, e.g. the combination of liquid state, conductivity and negligible vapor pressure.
Further information on the applications of ionic liquids can be found in the Technology section and in the following video:
