| | IRON (II) BROMIDE Usage And Synthesis |
| Chemical Properties | Yellow to dark brown lumps | | Chemical Properties | In contrast to the chloride, iron(III) bromide is unstable
under these conditions. The hydrated bromide can be dehydrated in a stream of hydrogen
bromide at 400°C. Iron(II) bromide forms a layer lattice of the CdI2 type. It has a magnetic
moment,μeff= 5·71 B.M. at 295°K. It is deliquescent and very soluble in water; the pale
green hexahydrate crystallizes at room temperature, the tetrahydrate above 49°C and the
dihydrate above 83°C. A 9-hydrate forms below -29·3°C. The anhydrous salt is also
soluble in ether, ethanol and acetonitrile. | | Uses | Iron(II) bromide is used as a polymerization catalyst. It is used in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. | | Preparation | Iron(II) bromide can be prepared by the direct reaction of bromine or hydrogen
bromide with iron at red heat. | | General Description | This product has been enhanced for catalytic efficiency. |
