; R
2
and R
3
are each independently either hydrogen or hydrocarbyl, R
2
and R
3
may be joined together with the N to form a heterocyclic group; R
4
is a divalent hydrocarbyl radical; and R
5
is hydrocarbyl; or a cation of the formula (II), N+HR6R7R8 (II) wherein R
6
is an alkanolyl group; R
7
is a hydrocarbyl group; and R
8
is either hydrogen or hydrocarbyl, or R
7
and R
8
may be joined together with the N to form a heterocyclic group.
The present invention relates to ionic liquid comprising an anion and a cation wherein the cation is a primary, secondary or tertiary ammonium ion containing a protonated nitrogen atom.
