ABSTRACT:
The invention relates to a method for producing ionic liquids and ionic solids which takes recourse to a novel, especially modular production process. According to the inventive method, those salts from an ionic carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate precursor (cationic synthesis module) are produced that comprise the desired quaternary ammonium, phosphonium, sulfonium or the analogous quaternary heteroaromatic cation. This precursor can be produced and stored efficiently and with a high degree of purity.
