Abstract
The present invention relates to a preparation method of ionic liquids, particularly to a one-step reaction method used for synthesizing quaternary ammonium compounds or quaternary phosphonium compounds. In the method, a nitrogenous or phosphorous compound, a proton compound, and a carbonate ester are added into a reactor simultaneously to synthesize corresponding the quaternary ammonium ionic liquid or the quaternary phosphonium ionic liquid through said one-step reaction, i.e., 'one-pot method' reaction, during which three reactants are involved. The present invention also provides a lithium ion secondary battery comprising the ionic liquid prepared by above-mentioned preparation method. The ionic liquid preparation method of the present invention can widen the choice range of raw materials needed when preparing ionic liquids, and further widen the synthesized ionic liquid species.
