| titleOfInvention | A production process and production system of lithium difluorophosphate |
| abstract | The invention discloses a production process of lithium difluorophosphate. The production process comprises: a preparation process of fluorophosphoric acid: reacting phosphorus pentoxide with anhydrous hydrogen fluoride to generate a fluorophosphoric acid solution, and the fluorophosphoric acid solution is obtained by distillation under reduced pressure Anhydrous fluorophosphoric acid solution; reaction process: the anhydrous fluorophosphoric acid solution and the mother liquor containing lithium hexafluorophosphate are passed into the third microchannel reactor to obtain a product stream containing lithium difluorophosphate; post-treatment process: filtering the Lithium phosphate product stream, the filtrate is heated and dried or crystallized at low temperature to obtain lithium difluorophosphate product. The invention has the advantages of high product purity, less impurities, high production efficiency, suitable for industrial production and the like. |
