Ionic liquids may be viewed as a new and remarkable class of solvents, or as a type of materials that have a long and useful history. A working definition suitable for a historical view of ionic liquids, and perhaps a practical view, is that an ionic liquid is a salt with a melting temperature below the boiling point of water. Most salts identified in the literature as ionic liquids are liquid at room temperature, and often to substantially lower temperatures. One fairly general feature of ionic liquids that is not part of the definition is that most have organic cations and inorganic anions. There are many synonyms used for ionic liquids that complicate a literature search. ‘Molten salts’ is the most common and most broadlyapplied term for ionic compounds in the liquid state. Unfortunately the term ‘ionic liquids’ was also used to mean the same thing long before there was much literature on low melting salts. It may seem that the difference between ionic liquids and molten salts is just a matter of degree (literally), however the practical differences are sufficient to justify a separately identified niche for the salts that are liquid around room temperature. That is, in practice the ionic liquids usually may be handled like ordinary solvents. There are also some fundamental features of ionic liquids, such as strong ion-ion interactions that are not often seen in higher temperature molten salts. Synonyms for materials that meet the working definition of ionic liquid are ‘room temperature molten salt’, ‘low temperature molten salt’, ‘ambient temperature molten salt’, ‘ionic fluid’ and ‘liquid organic salt’. Recently, room-temperature ionic liquids have received growing attention for various applications such as catalysis, electrochemistry, extractions, and owing to their unique physical and chemical properties, as support for nanoparticles. The physical properties of ILs strongly depend on the species of cation and anion and on the length of the alkyl groups o...
