1. An ionic liquid comprising:
at least a compound (a) wherein Compound (a) comprises one or more products of formula (I)
X+Y− Formula (I) wherein the anion Y− is an ether carboxylate anion or a mixture thereof of formula (II) wherein P consists of n units of —CH2CH2O— and m units of —CH2CHRO— or —CHRCH2O— wherein n represents a number from 2 to 8, m represents a number from 0 to 6, and the sum of n+m represents the average alkoxylation degree which corresponds to a number from 2 to 14; and wherein R represents an alkyl group having 1 to 2 carbon atoms; R1 represents a linear or branched alkyl having from 6 to 22 carbon atoms or a linear alkenyl group having 6 to 22 carbon atoms; and the cation X+ is an alkyl ammonium cation or a mixture thereof of formula (III) wherein R2 represents a linear or branched alkyl, a linear alkenyl or a linear alkynyl group having 6 to 24 carbon atoms, R3 represents a linear or branched alkyl group having 1 to 5 carbon atoms, R4 represents a linear or branched alkyl group having 1 to 5 carbon atoms, or a linear or branched alkyl, a linear alkenyl or a linear alkynyl group having 6 to 24 carbon atoms. |
