| Treatment | EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration. |
| 건강 영향 | Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses.

용도
출처
Magnesium bromide occurs in seawater, some mineral springs, natural brines, inland seas and lakes such as the Dead Sea and the Great Salt Lake, and salt deposits such as the Stassfurt deposits. In seawater, it is the primary source of bromine. By the action of chlorine gas upon seawater or seawater bitterns, bromine is formed. It is an electrolyte component in certain dry cells. In medicine, it is a sedative and anticonvulsant for treatment of nervous disorder. It also is used in organic synthesis forming several addition compounds.
제조 및 합성 방법
제조 방법
Magnesium bromide is prepared by treating MgO with hydrobromic acid and then crystallization above 0.0°C in solution. The product is the hexahydrate salt: MgO＋2HBr→MgBr2＋H2O→MgBr2·6H2O The anhydrous form may also be prepared by heating the hexahydrate with dry HBr gas. This compound can also be formed directly from the elements: Mg＋Br2→MgBr2
