Hexafluorophosphoric acid

CAS 16940-81-1: Hexafluorophosphoric acid

Description:Hexafluorophosphoric acid, with the CAS number 16940-81-1, is a strong inorganic acid characterized by its high acidity and the presence of six fluorine atoms bonded to a phosphorus atom. It is typically encountered as a colorless, fuming liquid that is highly corrosive and can release toxic fumes upon contact with moisture. This acid is known for its ability to act as a strong proton donor, making it a powerful acid in various chemical reactions. Hexafluorophosphoric acid is often used in the synthesis of fluorinated compounds and as a catalyst in organic reactions. Its salts, known as hexafluorophosphates, are commonly utilized in the production of ionic liquids and as electrolytes in batteries. Due to its highly reactive nature, it must be handled with care, using appropriate safety measures to avoid contact with skin or inhalation of vapors. Overall, hexafluorophosphoric acid is a significant compound in both industrial and research applications, particularly in the field of fluorine chemistry.
