1. A process for dissolving an organic, inorganic, or biological material, the process comprising contacting the organic, inorganic, or biological material with an ionic liquid, the ionic liquid comprising an anion and a cation characterised in that the cation is a tertiary nitrogen-containing cation of the formula (I) wherein: R is a hydrocarbyl group optionally interrupted by one or more ether or thioether linkages, and substituted with one or more substituents selected from nitrogen-containing functional groups, alkenyl, alkoxy, carbonyl and carboxyl groups; or from thiol, alkythio, sulphonyl, thiocyanate, isothiocyanate, azido, hydrazino, halogen, boronate and silyl groups; R′ and R″, which may be the same or different, each represent H or a hydrocarbyl group optionally interrupted by one or more ether or thioether linkages, and optionally substituted with one or more substituents selected from nitrogen-containing functional groups, alkyl, alkenyl, alkoxy, hydroxy, carbonyl and carboxyl groups; or from thiol, alkythio, sulphonyl, thiocyanate, isothiocyanate, azido, hydrazino, halogen, boronate and silyl groups; and any two or three of R, R′ and R″ may be joined together with the N to form a cyclic group.
