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.
일반 설명
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.
