| titleOfInvention | The method of synthesizing and refining ionic liquid [E1Mim2][NTf2] |
| abstract | The present invention relates to a method for synthesizing and refining ionic liquid [E 1 Mim 2 ][NTf 2 ], the dimethylformamide solution of dibromodiethyl ether and the dimethylformamide solution of 1-methylimidazole are mixed in a certain Reaction under the condition of; Solvent dimethylformamide is then recycled by rectification, and the product is an intermediate ionic liquid containing dimethylformamide and 1-methylimidazole; the dimethylformamide in the intermediate ionic liquid is extracted by extraction The amide and 1-methylimidazole are separated, and the extractant is dichloromethane; the dichloromethane in the product intermediate ionic liquid is removed by rectification, so as to obtain a pure intermediate ionic liquid; the intermediate product ionic liquid and bistrifluoromethanesulfonyl Aqueous solution of lithium amine reacts, the precipitate is removed by a centrifuge, and a small amount of water is removed by drying to obtain the target product. The invention has the characteristics of short technological process and simple operation, the yield reaches 92.0%, and the purity reaches more than 99.0%. |
