Kyselina difluorofosforečná je anorganická sloučenina se vzorcem HPO2F2, difluorovaný derivát kyseliny trihydrogenfosforečné; vytváří soli nazývané . Za standardních podmínek jde o bezbarvou kapalinu. Tato kyselina má omezené využití, což je částečně způsobeno její tepelnou a hydrolytickou nestabilitou. Připravuje se hydrolýzou : POF3 + H2O → HPO2F2 + HF Další hydrolýzou vzniká : HPO2F2 + H2O → H2PO3F + HF Produktem úplné hydrolýzy je kyselina fosforečná: H2PO3F + H2O → H3PO4 + HF (cs) 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 + HF Further hydrolysis gives monofluorophosphoric acid: HPO2F2 + H2O → H2PO3F + HF Complete hydrolysis gives phosphoric acid: H2PO3F + H2O → H3PO4 + HF The salts of difluorophosphoric acid are known as difluorophosphates.
