Research output: Patent


The present invention relates to a method for synthesizing an ionic liquid from a first precursor in the form of a salt including an anion and a cation, and second precursor in the form of a salt including an anion and a cation, characterized in that it includes an anion metathesis step of causing a metathesis reaction between the cation of the first precursor and the anion of the second precursor at a temperature no less than the melting temperature of the cation of the first precursor, such that the first precursor forms a solvent that dissolves the second precursor. The invention can be used in the synthesis of ionic liquids in various fields, and in particular for solvents used in microelectronics, as well as in the separation of gaseous mixtures, in the electrolytic deposition of metals, or for electrolytes, specifically for lithium-ion batteries.
