If HF alone is electrolyzed, hydrogen forms at the cathode (positive part of the cell) and the fluoride ions remain in solution. After electrolysis, potassium fluoride remains in solution. [35] 2 HF 2 − → H 2 ↑ + F 2 ↑ + 2 F −. The modern version of the process uses steel containers as cathodes, while blocks of carbon are used as anodes.
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 fluorosilicate is a chemical compound with the chemical formula K 2 [SiF 6]. When doped with potassium hexafluoromanganate(IV) ( K 2 [MnF 6 ] , with Mn 4+ ) it forms a narrow band red producing phosphor , (often abbreviated PSF or KSF), of economic interest due to its applicability in LED lighting and displays .
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 ...
