Ionic Liquids

摘要

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 R¹ is a group -R⁴-O-R⁵; R² and R³ are each independently either hydrogen or hydrocarbyl, R² and R³ may be joined together with the N to form a heterocyclic group; R⁴ is a divalent hydrocarbyl radical; and R⁵ is hydrocarbyl; or a cation of the formula (II), N+HR6R7R8 (II) wherein R⁶ is an alkanolyl group; R⁷ is a hydrocarbyl group; and R⁸ is either hydrogen or hydrocarbyl, or R⁷ and R⁸ may be joined together with the N to form a heterocyclic group.
