Fluorinating agent in organic chemistry. | [Hazard]
Toxic material. | [Description]
The manganese fluoride, MnF3, is preferably formed by fluorination of manganese(III) iodide. It is a solid, and although its decomposition pressure is lower than 10.1325kPa (0.1 atmosphere) at 600°C, fluorine is still released when heated. It is a strong fluorinating agent, which acts with sulfur, boron, silicon, carbon, phosphorus trichloride and carbon tetrachloride when heated. It is used to fluoride gaseous hydrocarbons. | [Preparation]
Manganese(III) fluoride can also be formed via the reaction of elemental fluorine with a manganese(II) halide at around 250°C. | [General Description]
Manganese(III) fluoride (also known as manganese trifluoride), MnF3, is a red/purplish solid useful for converting hydrocarbons into fluorocarbons, that is, it is a fluorination agent. It forms a hydrate and numerous derivatives. MnF3 can be produced by reacting a solution of MnF2 in hydrogen fluoride with fluorine. | [Synthesis]
Dissolve Mn2O3 in hydrofluoric acid and concentrate the solution for crystallization, or reduce potassium permanganate in hydrofluoric acid with low manganese salt to obtain hydrated manganese fluoride MnF3·3H2O. This compound is soluble in cold water and does not decompose, and is stable in hot water in the presence of hydrofluoric acid. Anhydrous manganese trifluoride is slowly decomposed into manganese difluoride, hydrated manganese dioxide and hydrogen fluoride in water.
