Abstract

The invention relates to an ionic liquid, comprising the association of a cation, chosen from the following cations of formulas (I) to (III): in which: —R1 to R4 for formulas (I) and (II), and R1 to R3 for formula (III) represent, independently from one another, a hydrogen atom or an aliphatic or cyclic hydrocarbon group, under the condition that at least one of the groups R1 to R4, for formulas (I) and (II) and at least one of the groups R1 to R3 for formula (III) represents an aliphatic hydrocarbon group comprising at least two carbon atoms and at least one of the groups R1 to R4 for formulas (I) and (II) and at least one of the groups R1 to R3 for formula (III) represents a hydrogen atom; and an anion chosen from the following anions of formulas (IV) and (V): in which: —R5 is a cyclic hydrocarbon group; —n1 is an integer equal to 1, 2, 3, 4, 5 or 6; and—n2 is an integer equal to 1, 2, 3 or 4.
