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.
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. Bromate is also a potential carcinogen. (L625, L626, L627, L638)
Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes. (L626, L627, A543)
Bromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)
Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)
使用Oxidizing agent.
使用用途臭素酸や臭素酸の塩は基本的に、酸化剤として使用されます。具体的には、合成原料、医薬品原料、染料の合成反応の中間処理剤として用いられる場合が多いです。 例えば、臭素酸カリウムは食品添加物 (小麦粉品質改良剤、魚肉製品添加剤) 、分析試薬に使用されます。また、臭素酸ナトリウムは医薬部外品添加物 (パーマネントウェーブ用剤) 、試薬などの用途があります。 ただし、臭素酸は強酸性、強酸化剤のため人体に有毒です。皮膚、眼、粘膜を侵すので、取り扱いに注意を要します。
製造方法Bromic acid is prepared by adding sulfuric acid to barium bromate.Ba(BrO3)2 + H2SO4 → 2HBrO3 + BaSO4The product is distilled and absorbed in water. A 50% solution may be obtained by slow evaporation of the dilute solution in vacuum at -12°C.
