iron tribromide - Reference Information
| physico-chemical properties | Iron bromide, brownish yellow or dark red-brown solid. Soluble in water, soluble in water slightly acidic, its aqueous solution can crystallize dark green FeBr3 · 6H2O. Soluble in electron-donating solvents (e. G. Ether, ethanol). Solid iron bromide has a polymer structure similar to that of ferric chloride, with each iron atom having a six-coordinate, octahedral structure, attached to six bromine atoms. |
| preparation | Iron bromide can be prepared by reacting iron with bromine: 2Fe X 3Br2 → 2fefr3 Iron bromide can also be obtained by reacting with bromine at 170-200°C: 2FeBr2 Br2 → 2FeBr3 |
| catalytic reaction | Iron bromide can catalyze the reaction of benzene and liquid bromine to bromobenzene: The Iron bromide sample is difficult to purify because it is unstable and the Br − is oxidized by Fe3 to form Br2 and Fe2. Iron bromide is easy to decompose when heated to 200 ° C. Or higher, and its aqueous solution is also decomposed by boiling to generate ferrous bromide and bromine. 2FeBr3 →2FeBr2 Br2 |
