A kind of preparation method of fluorine-containing dibasic acid fluoride |
| abstract |
The invention discloses a preparation method of fluorine-containing dicarboxylic acid fluoride. The preparation method takes fluorine-containing dicarboxylic acid as a raw material, and under the action of a solvent and a catalyst, undergoes a fluorination reaction with a fluorinating reagent to obtain a fluorine-containing dicarboxylic acid. Acid fluoride. In actual production, fluorine-containing dicarboxylic acids are directly fluorinated into corresponding fluorine-containing diacid fluorides under the action of organic solvents and Lewis acid catalysts. The use of organic solvents and specific catalysts, combined with other conditions, can effectively promote the production of fluorine-containing dicarboxylic acids. Fluorodicarboxylic acids generate the corresponding acid fluorides with high conversion. |
