The present invention relates to a method for synthesizing ionic liquids comprising a carbonate functional group characterized in that it comprises a step of reaction A without addition of lithium between a first reactant selected among an imidazolium, a pyrrolidinium or an ammonium and a second reactant being a methyl formate imidazolium. The first reactant is an imidazolium alcohol, a pyrrolidinium alcohol 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 in the production of ionic liquids which can be used in lithium batteries with a graphite electrode.
本发明涉及一种合成含有碳酸酯官能团的离子液体的方法,其特征在于该方法包括一个步骤,即在不添加锂的情况下,在选自咪唑、吡咯烷或铵的第一反应物和甲酸甲酯咪唑的第二反应物之间进行反应 A。第一反应物是咪唑醇、吡咯烷醇或醇铵盐,其阴离子为 NTf2。第二个反应物是甲酸氯甲基咪唑鎓。
该方法可应用于绿色化学领域,更具体地说,可用于石墨电极锂电池的离子液体的生产。
