Procedure
The onium cation can be chosen so as to introduce, into the salt, substituents which make it possible to confer specific properties on the said salt. For example, the M+ cation can be a cationic heterocycle of aromatic nature comprising at least one quaternized nitrogen atom in the ring. Mention may be made, by way of example, of the imidazolium, triazolium, pyridinium and 4-(dimethylamino)pyridinium ions, the said cations optionally carrying a substituent on the carbon atoms of the ring. Among these cations, those which give a salt with a melting point of less than 150° C. are advantageous, because they give ionic compositions which have a protonic conduction. A particularly preferred composition with protonic conduction comprises a salt in which the cation is formed by addition of a proton to the nitrogen of an imidazoline, of an imidazole or of a triazole, as well as the corresponding nitrogenous base, in a proportion of 0.5 to 10 by molar ratio.
