Direct synthesis of ammonium monofluorophosphate monohydrate, [NH4]2[PO3F]·H2O and potassium monofluorophosphate, K2[PO3F]
Abstract
A new direct general method for the synthesis of crystalline [NH4]2[PO3F]·H2O and K2[PO3F], based on the reaction of H3PO4 and AHF2(A = NH4 or K) followed by precipitation with ethanol, is described. The identity of the compounds has been established from the results of elemental analyses, molar conductance measurements, i.r. and laser Raman spectroscopic studies. Advantages of the new method are highlighted.
