| MANGANESE(III) FLUORIDE Usage And Synthesis |
| 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. | | Chemical Properties | purple powder or crystals | | Uses | Fluorinating agent in organic chemistry. | | Uses | It is used as a fluorinating agent, useful for conversion of hydrocarbons into fluorocarbons. It is used in organic synthesis as Lewis acid to prepare a number of organic compounds. | | Hazard | Toxic material. | | 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. |
