Potassium hexafluorophosphate Chemical Properties,Uses,Production
Description
Potassium hexafluorophosphate, abbreviated as KPF6, is a associated electrolyte. In battery systems, it acts as an electrolyte additive in anode-less lithium metal batteries, lithium-sulphur batteries and solid-state batteries; by forming a protective shielding effect and modulating the solid-state electrolyte interface, it enhances cycling stability, ionic conductivity and electrochemical performance [1-3]. In perovskite solar cells, KPF6 is used as an interface modification material; by treating the SnO2 quantum dot/perovskite interface, it can passivate defects and enhance stable photoconversion efficiency [4].
Chemical Properties
white crystalline powder
Uses
A soluble neutral salt, Potassium hexafluorophosphate can be used for synthesis.
Uses
Potassium Hexafluorophosphate is used in preparation of Moxifloxacin derivatives and its application.
Preparation
Potassium hexafluorophosphate is prepared by reacting phosphorus pentachloride, potassium chloride, and hydrofluoric acid in liquid hydrogen fluoride. The reaction equation is: PCl₅ + KCl + 6HF → KPF₆ + 6HCl.
Hazard
Toxic by ingestion.
Purification Methods
Crystallise it from alkaline aqueous solution, using polyethylene vessels, or from 95% EtOH, and dry it in a vacuum desiccator over KOH. [Kloditz Z Anorg Allgem Chem 284 144 1956, Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 196 1963.]
