METHOD FOR SYNTHESISING IONIC LIQUIDS HAVING A CARBONATE FUNCTIONAL GROUP AND RESULTING IONIC LIQUIDS.

摘要

The present invention relates to a method for synthesising ionic liquids comprising a carbonate functional group characterized in that it comprises a reaction step A without addition of lithium between a first reactant chosen from an imidazolium, a pyrrolidinium or an ammonium and a second reactant being a methyl formate imidazolium. The first reactant is an imidazolium alcohol salt, a pyrrolidinium alcohol salt or an ammonium alcohol salt, the anion of which is NTf2. The second reactant is a chloromethyl formate imidazolium. The application of this method will be found in the field of green chemistry and more specifically for the production of ionic liquids that can be used in lithium batteries with a graphite electrode.
