The invention provides ionic liquids and processes for
their preparation. The liquids may either comprise a
cation of the formula (I); N+HR1R2R3 (I) wherein Rl is a
group-R4-O-R5; R2 and R3 are each independently either
hydrogen or hydrocarbyl, or R2 and R3 may be joined
together with the N to form a heterocycl...
