| Ammonium hexafluorophosphate Usage And Synthesis |
| Description |
Ammonium hexafluorophophate can be used to for the synthesis of non-aqueous polymer gel electrolytes based on polyethylene oxide (PEO), which show high conductivity above 10-2 S/cm at 25°C.1 It can be used to prepare other hexafluorophosphate.2 It is also used for the synthesis of ruthenium and palladium complexes.3

| Purification Methods |
It crystallises from H2O in square plates and decomposes on heating before melting. Its solublility in H2O at 20o is 74.8% w/v, and it is very soluble in Me2CO, MeOH, EtOH and MeOAc but is decomposed by boiling mineral acids.
