Potassium hexafluorophosphate is the chemical compound with the formula KPF6. This colourless salt consists of potassium cations and hexafluorophosphate anions. It is prepared by the reaction: PCl5 + KCl + 6 HF → KPF6 + 6 HCl This exothermic reaction is conducted in liquid hydrogen fluoride. The salt is stable in hot alkaline aqueous solution, from which it can be recrystallized. The sodium and ammonium salts are more soluble in water whereas the rubidium and caesium salts are less so.

(de) ヘキサフルオロリン酸カリウム(Potassium hexafluorophosphate)は、化学式がKPF6の無機化合物である。無色の固体で、カリウムイオンとヘキサフルオロリン酸イオンを含む。五塩化リンと塩化カリウムとフッ化水素との反応で合成される。この発熱反応は液体のフッ化水素中で行われる。生成した塩は熱アルカリ水溶液中でも安定であるため、それで再結晶することができる。水への溶解度では、ナトリウム塩およびアンモニウム塩より小さく、およびより大きい。 KPF6は研究室では、親油性の塩を与えるヘキサフルオロリン酸イオンの供給源である。しかし、この塩はより溶解度が低いことがある。 (ja) Kaliumhexafluorfosfaat (KPF6) is het kaliumzout van hexafluorfosforzuur. Het anorganisch zout bestaat uit een kaliumion (K+) en een hexafluorfosfaation (PF6−). De stof is in laboratoria een grote bron van het hexafluorfosfaation.

(ru) 六氟磷酸钾是化學式為KPF6的無機化合物，是無色的鹽類，由鉀離子和六氟磷酸根離子組成。可以由以下的化學反應來製備： PCl5 + KCl + 6 HF → KPF6 + 6 HCl 此放熱反應在液體的氟化氫中進行。六氟磷酸钾可溶於熱的鹼性溶液中，并可以用该溶液重结晶。六氟磷酸根的鈉鹽和銨鹽在水中的溶解度比較高，而銣鹽及銫鹽的溶解度比較低。 KPF6是實驗室常見的六氟磷酸離子來源，六氟磷酸離子是非配位陰離子，因此會使其鹽類有親脂性，六氟磷酸鹽的溶解度比密切有關的四氟硼酸盐要小。 (zh) Kalia heksafluoro-fosfato estas kemia neorganika kombinaĵo, senkolora aŭ blanka solidaĵo konsistanta je kaliaj katjonoj (K+ kaj heksafluorofosfataj anjonoj (PF6+).

Il s'agit d'un sel de cations potassium K+ et d'anions hexafluorophosphate PF6−. On le prépare habituellement par la réaction : PCl5 + KCl + 6 HF → KPF6 + 6 HCl, réaction exothermique réalisée dans le fluorure d'hydrogène liquide. Ce sel est stable dans les solutions aqueuses alcalines chaudes, à partir desquelles il peut être recristallisé. Les sels de sodium Na+ et d'ammonium NH4+ sont davantage solubles dans l'eau que le sel de potassium, lui-même plus soluble que les sels de rubidium Rb+ et de césium Cs+. (fr)
