| | 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

| | Chemical Properties | off-white powder | | Uses | Ammonium hexafluorophosphate is used as a preservative. It is used as a starting material in the preparation of other hexafluorophosphates. Further, it is used in synthesis of organometalic compounds, especially rhodicinium hexafluorophosphate, which has inert and non-coordinating counter ion. | | Uses | Ammonium hexafluorophosphate is used to synthesize polyethylene oxide based highly conductive non aqueous polymer gel electrolytes exhibiting high conductivity (>10-2S/cm at 25oC) | | Uses | Ammonium hexafluorophosphate (NH4PF6) can be used as a precursor for the preparation of:
- Metal complexes, particularly iridium and rhodium complexes.???????
- Flame retardant cellulose-based materials.???????
- Cyclic amidinium and iminium ammonium hexafluorophosphate salts.????????
- The polymer-supported iridium isomerization catalyst for the selective trans isomerization of aryl allylic derivatives.
| | General Description | Ammonium hexafluorophosphate decomposes on heating before melting. Solubility of ammonium hexafluorophosphate in H2O at 20oC is 74.8% w/v. Additionally, it is very soluble in Me2CO, MeOH, EtOH and MeOAc, and is decomposed by boiling mineral acids. | | 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.
