Chemistry & industry
Applications
UsesIron(II) fluoride is used for proteomics research applications. It is also a chemical intermediate.
UsesIron(II) fluoride is used as a catalyst in organic fluorination reactions. Other applications are in ceramics; and in the preparation of fluoride salts of other metals.
Preparation methods
PreparationAnhydrous iron(II) fluoride may be prepared by passing hydrogen fluoride gas over iron at a high temperature: 2HF + Fe → FeF2 + H2 Alternative methods of preparation of anhydrous salt involve the reduction of iron(III) fluoride with hydrogen; or by passing fluorine gas over anhydrous iron(II) chloride in the cold: 2FeF3 + H2 → 2FeF2 + 2HF FeCl2 + F2 → FeF2 + Cl2 The tetrahydrate may be prepared by dissolving iron metal in aqueous hydrofluoric acid.
