Potassium fluoride gives 2-chloro-1-fluoro-4-nitrobenzene, an intermediate in the production of herbicides. With ammonia , one obtains 2-chloro-4-nitroaniline, a precursor to diazo dyes. Reduction with iron powder gives 3,4-dichloroaniline (m.p. 72 °C, CAS# 95-76-1).
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.
The mass ratio of the solvent and potassium fluoride is 1.1~2.0 : 0.5~1. When the reaction temperature of 100~160 °C is reached, methyl chloroacetate ClCH 2 CO 2 CH 3 is continuously added in the reactor at a speed of 5~10 kg/min with the mass ratio of methyl chloroacetate and potassium fluoride being 1:0.5～1. The reaction between these ...
Three crystalline phases of ZrF 4 have been reported, α , β (tetragonal, Pearson symbol tP40, space group P42/m, No 84) and γ (unknown structure). β and γ phases are unstable and irreversibly transform into the α phase at 400 °C. [3] Zirconium(IV) fluoride forms several hydrates. The trihydrate has the structure (μ−F) 2 [ZrF 3 (H 2 O ...
Oxygen difluoride was first reported in 1929; it was obtained by the electrolysis of molten potassium fluoride and hydrofluoric acid containing small quantities of water. [7] [8] The modern preparation entails the reaction of fluorine with a dilute aqueous solution of sodium hydroxide, with sodium fluoride as a side-product:
