Potassium bifluoride is the inorganic compound with the formula K[HF 2]. This colourless salt consists of the potassium cation (K +) and the bifluoride anion ([HF 2] −). The salt is used as an etchant for glass. Sodium bifluoride is related and is also of commercial use as an etchant as well as in cleaning products. [3]

Anhydrous fluoride salts, which are easier to handle than fluorine gas, can be produced in a cyclotron. [8] To achieve this chemistry, the [18 F]F − is separated from the aqueous solvent by trapping it on an ion-exchange column, and eluted with an acetonitrile solution of 2,2,2-cryptand and potassium carbonate.
Potassium hexafluoroarsenate can be prepared by direct action of arsenic pentafluoride and potassium fluoride: AsF 5 + KF → KAsF 6. Also, it can be synthesized by the action of hydrofluoric acid on arsenic pentafluoride in the presence of potassium perbromate: [4] KBrO 4 + 3HF + 2AsF 5 + KF → KAsF 6 + AsF 6 [H 3 O]
[18] [39] The first organofluorine compound was discovered in 1835, when Dumas and Péligot distilled dimethyl sulfate with potassium fluoride and got fluoromethane. [39] [40] In 1862, Alexander Borodin pioneered a now-common method of halogen exchange: he acted on benzoyl chloride with potassium bifluoride and first synthesized benzoyl fluoride.
