TFA is prepared industrially by the electrofluorination of acetyl chloride or acetic anhydride, followed by hydrolysis of the resulting trifluoroacetyl fluoride: [4] CH 3 COCl + 4 HF → CF 3 COF + 3 H 2 + HCl CF 3 COF + H 2 O → CF 3 COOH + HF. Where desired, this compound may be dried by addition of trifluoroacetic anhydride. [5]
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]
Potassium hexafluoronickelate(IV) is an inorganic compound with the chemical formula K 2 NiF 6. It can be produced through the reaction of potassium fluoride, nickel dichloride, and fluorine. It reacts violently with water, releasing oxygen. It dissolves in anhydrous hydrogen fluoride to produce a light-red solution.
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]
