PROCESS FOR THE SYNTHESIS OF IONIC LIQUIDS WITH CARBONATE FUNCTIONAL GROUP AND IONIC LIQUIDS THUS OBTAINED

摘要

The present invention relates to a process for the synthesis of ionic liquids comprising a carbonate functional group characterized in that it comprises a reaction step A without the 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 a salt of imidazolium alcohol, pyrrolidinium alcohol or ammonium alcohol whose anion is Ntf2. The second reactant is a chloromethyl formate imidazolium This method will find application in the field of green chemistry and more specifically for the production of ionic liquids used in lithium batteries with graphite electrode.
