AI Technical Summary
Existing methods for preparing lithium hexafluorophosphate suffer from low yields and high requirements for reaction equipment, resulting in high costs for industrial production.
Lithium hexafluorophosphate is prepared by metathesis, using phosphoric acid to extract the organic phase as raw material. Potassium hexafluorophosphate is generated by the reaction of phosphoric acid and hydrofluoric acid, and then reacted with lithium chloride and catalyst to generate lithium hexafluorophosphate. This method avoids gas mixing and reduces equipment requirements.
It improves the yield of lithium hexafluorophosphate, reduces the corrosiveness requirements of equipment and production costs, reduces environmental pollution, and simplifies equipment design.
