Abstract
In general, an ionic liquid is a liquid that consists only of ions. However, the term “ionic liquid” includes an additional special definition to distinguish it from the classical definition of a molten salt. While a molten salt is generally thought to be a high-melting and highly viscous medium, ionic liquids are already liquid at low temperatures (< 80 °C) and have relatively low viscosity. The apparently somewhat arbitrary line draw between a molten salt and an ionic liquid at a melting point of 80 °C can be justified by the abrupt improvement of the applicability of the liquid salts below 80°C. Only a liquid range below this temperature can enable the substitution of conventional organic solvents by ionic liquids.
