GALLIUM BROMIDE - Reference Information
| Physical and chemical properties | Gallium bromide (GaBr3) is a compound and one of the four gallium halides (English: gallium halides). Gallium bromide is a white solid that reacts with water. Solid gallium bromide is stable at room temperature and mainly exists as a dimer. |
| solubility | easy to absorb moisture, easily soluble in water, benzene, carbon tetrachloride and carbon disulfide. |
| Use | Gallium bromide is used as a catalyst for alkylation of aromatic compounds at low temperatures. |
| Preparation | One way to prepare GaBr3 is to heat the element gallium in the presence of liquid bromine under vacuum. After the highly exothermic reaction, the mixture is allowed to stand and then various purification steps are performed. Since the beginning of the 20th century, this method is still a useful method for preparing GaBr3. Historically, gallium was obtained by electrolyzing hydroxides in KOH solutions, but today it is obtained as a by-product of aluminum and zinc production. GaBr3 can also be formed by the combination of Ga(s) and Br(g) in an anhydrous, oxygen-free, organic and grease-free environment. The reaction product is a gas and must be crystallized to form a GaBr3 solid purchased in the laboratory: Ga(s) 3Br(l) → GaBr3(g) |
