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]
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 ...
Zirconium(IV) fluoride describes members of a family inorganic compounds with the formula Zr F 4 (H 2 O) x. All are colorless, diamagnetic solids. All are colorless, diamagnetic solids. Anhydrous Zirconium(IV) fluoride is a component of ZBLAN fluoride glass .
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:
