1. What is Potassium fluoride?
Potassium fluoride (CAS NO.7789-23-3) is a white powder or crystals with a sharp saline taste. You kown that the potassium fluoride formula is KF. Clocat F or Potassium fluoride (KF) are all the name of this inorganic chemical. 99.5% Potassium fluoride means that the material contains the KF on 99.5%. 165892-23-9 and 59217-74-2 are all the deleted CAS of this chemical. Potassium fluoride on alumina (KF/Al2O3) is a chemical agent constisting of potassium fluoride and aluminium oxide. It is a base which is used in organic synthesis.
2. How can we get the 99.5% Potassium fluoride?
You can let the KOH to react with the HF to get the Potassium fluoride (KF). The specific step of this reaction is showed below:
