| titleOfInvention | A kind of preparation method and application of lithium 2-fluoromalonate difluoroborate |
| abstract | The invention provides a preparation method of lithium 2-fluoromalonate difluoroborate, comprising the following steps: (1) performing an alkaline hydrolysis reaction on 2-fluoromalonate diester and lithium hydroxide aqueous solution to obtain 2-fluoromalonate Lithium malonate aqueous solution; (2) after concentrating the 2-fluoro lithium malonate aqueous solution prepared in step (1), vacuum drying is carried out to obtain 2-fluoro lithium malonate; (3) step (2) The prepared 2-fluoromalonate lithium and boron trifluoride complex are reacted in an organic solvent to obtain an organic solution of 2-fluoromalonate lithium difluoroborate; (4) in step (3) The prepared organic solution of lithium 2-fluoromalonate difluoroborate is filtered, recrystallized and dried to obtain the product lithium 2-fluoromalonate difluoroborate. The present invention improves the yield and purity of the product by improving the preparation method. |
