| 20080251759 | Method For Producing Ionic Liquids, Ionic Solids Or Mixtures Thereof - 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. The actual process for producing the desired ionic compound, which comprises the introduction of the desired anion, is, unlike generic production processes known so far, flexible, fast and generally applicable. In a preferred embodiment, the carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate anion is completely removed in the form of a gaseous carbon dioxide by reaction with any Brønsted acid (anionic synthesis module) and is replaced by the anion that is conjugated to acid. The invention thus allows the production of a plurality of varied ionic liquids and ionic solids on the basis of any industrially producible ionic precursor in a fast and efficient manner (modular production method). In another embodiment, the same ionic carbonate precursors that comprise the desired quaternary ammonium, phosphonium, sulfonium, or analogous quaternary heteroaromatic cation are reacted with suitable metal salts (e.g. calcium, strontium, barium, zinc or manganese salts), whereby the carbonate anion of the precursor interacts with the metal cation to give a poorly soluble carbonate (e.g. calcium, strontium, barium, zinc or manganese carbonate) which is then precipitated. The carbonate of the ionic precursor is replaced (metathesis reaction) by the anion of the added suitable metal salt (anionic synthesis module) and the desired ionic compound can be isolated by filtration once the poorly soluble carbonates are removed. | 10-16-2008 |
