Difluorophosphoric acid, anhydrous
Difluorophosphoric acid is an inorganic compound with the formula HPO2F2. It is a colorless liquid. The acid has limited applications, in part because it is thermally and hydrolytically unstable.It is prepared by hydrolysis of phosphorus oxyfluoride: POF3 + H2O → HPO2F2 + HFFurther hydrolysis gives monofluorophosphoric acid: HPO2F2 + H2O → H2PO3F + HFComplete hydrolysis gives phosphoric acid: H2PO3F + H2O → H3PO4 + HFThe salts of difluorophosphoric acid are known as difluorophosphates.
