| production method | manganese, manganese carbide or manganese chloride can directly interact with fluorine to obtain a mixture of MnF2 and MnF3. While manganese iodide (Ⅱ) interacts with fluorine to obtain pure MnF3. When MnF3 is heated, it loses part of fluorine and generates low-valent fluoride. Fluoride high manganese MnF3, preferably formed by manganese iodide (Ⅲ) fluorination. It is a solid. Although its decomposition pressure is lower than 10.1325kPa(0.1 atmosphere) at 600 ℃, it still emits fluorine when heated. It is a strong fluorinating agent, which interacts with sulfur, boron, silicon, carbon, phosphorus trichloride and carbon tetrachloride when heated. It is used to fluorinate gaseous hydrocarbons. Dissolve Mn2O3 in hydrofluoric acid and concentrate and crystallize this solution, or reduce potassium permanganate in hydrofluoric acid with a 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. |
