Health Effects · 1 件

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.

Toxicity Summary · 2 件

IDENTIFICATION AND USE: Hydrogen bromide (HBr) is a colorless gas. It is utilized in the production of inorganic bromides and organic bromides, in reaction with alkynes to form bromoalkenes, opening epoxides and lactones, as a catalyst for oxidations, and in alkylations and condensations in organic chemistry. It is also used in analytical chemistry, and as a solvent for ore minerals. HUMAN STUDIES: Nose and throat irritation occurred in human subjects exposed to HBr for several minutes at concentrations of 3 ppm (1 of 6 subjects) and 4 ppm (3 of 6 subjects) respectively for several minutes. No effects were observed at 2 ppm, but detectable odor was noted at all exposure levels (2 to 6 ppm). No eye irritation was noted. The odor threshold is given as 6.667 mg/cu m and the irritating concentration as 10.00 mg/cu m. Concentrations of 0.13-0.2% are lethal. HBr is also corrosive to skin and mucous membranes and can cause severe burns. Exposure to high concentrations may result in dermatitis. Severe exposures result in pulmonary edema, and often laryngeal spasm. Ingestion causes burns of mouth and stomach. A 60-year-old laboratory technician developed pulmonary infiltrates consistent with chemical pneumonitis following accidental exposure to a mixture of hydrogen bromide and phosphorus tribromide. Two patients developed acute pneumonitis followed by reactive airways dysfunction syndrome after bathing in a hot tub. Bromine and hydrobromic acid generated from a widely used water disinfectant were implicated as the underlying cause. ANIMAL STUDIES: In rats, tissue injury following nose-breathing exposure to HBr was confined to the nasal region. However, mouth-breathing exposure in rats caused higher mortality rates and major tissue disruption in the trachea, including epithelial, submucosal, glandular, and cartilage necrosis, and accumulations of inflammatory cells and exudates. More peripheral lung damage was manifested by lung gravimetric increases and histopathologic changes primarily in the larger conducting airways. HBr causes more severe burns to rat skin than hydrogen chloride or hydrogen iodide.

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)

Effluent Concentrations · 1 件

By dissolving hydrogen bromide in water or by distilling from a mixture of sodium bromide and 50% sulfuric acid. /Hydrobromic acid/

The anhydrous gas is produced industrially by burning bromine in the presence of excess hydrogen at 500 °C or by reacting bromine with hydrogen at 375 °C over platinized silica gel or platinized asbestos catalyst. Generation of hydrogen bromide as a byproduct during bromination of aromatic compounds is another major source of the industrial gas, although the hydrogen bromide is less pure. In either case, entrained bromine can be removed by scrubbing with phosphorous acid or by activated carbon. The gas is liquefied by compression for storage and shipment in cylinders. Methods for laboratory preparation include reaction of bromine with 1,2,3,4-tetrahydronaphthalene at 20 °C or by the reaction of bromine with sulfur dioxide and water followed by distillation.

Constant-boiling hydrobromic acid distills at 124.3 °C at atmospheric pressure and contains 47.63 wt% hydrogen bromide. The boiling point and hydrogen bromide concentration can be partially controlled by varying the pressure during distillation. These solutions are produced industrially by dissolution of hydrogen bromide in water.

説明Hydrobromic Acid is a strong acid formed by dissolving the diatomic molecule HBr in water. “Constant-boiling” hydrobromic acid is an aqueous solution that distills at 124.3°C and contains 47.6% HBr by weight. Hydrobromic acid has a pKa of 9, making it a stronger acid than hydrochloric acid, but not as strong as HI, hydroiodic acid. Hydrobromic acid is one of the strongest mineral acids known. Hydrobromic acid is mainly used for the production of inorganic bromides, especially the bromides of zinc, calcium, and sodium. It is a useful reagent for generating organobromine compounds. Certain ethers are cleaved with HBr. It also catalyzes alkylation reactions and the extraction of certain ores. Industrially significant organic compounds prepared from hydrobromic acid include allyl bromide, tetrabromobis(phenol), and bromoacetic acid. Hydrobromic acid can be prepared in the laboratory via the reaction of Br2, SO2 and water. Another laboratory preparation involves the production of anhydrous HBr, which is then dissolved in water. Hydrobromic acid has commonly been prepared industrially by reacting bromine with either sulfur or phosphorous and water. However, it can also be produced electrolytically. It can also be prepared by treating bromides with nonoxidizing acids like phosphoric or acetic acids. Hydrobromic acid is available commercially in various concentrations and purities.

使用Hydrogen bromide is used as a reagent and catalyst in several types of organic reactions such as the formation of alkyl bromides from alcohols.It is also used as a source material in the preparation of inorganic bromides. Hydrogen bromide serves as a catalyst in alkylation reactions. It has also been reportedly used in the controlled oxidation of aliphatic and alicyclic hydrocarbons to peroxides, ketones, and acids. In organic synthesis, hydrogen bromide is used to substitute bromine for aliphatic chlorine in the presence of aluminum catalyst.

一般的な説明Hydrobromic acid solution (HBr) is a clear, yellow or brown colored liquid. Its reaction with K has been studied by a molecular beam technique.

製造方法Hydrogen bromide gas may be produced by combustion of hydrogen inbromine vapor at 37.5°C using a catalyst such as platinized asbestos or pla-tinized silica gel. Unreacted free bromine is removed from the product bypassing the gaseous product mixture over hot activated charcoal. Hydrogenbromide formed may be absorbed in water to obtain the acid; or may be cooledand liquefied for shipment in cylinders. Hydrobromic acid may be prepared in the laboratory by distillation of asolution of potassium bromide with dilute sulfuric acid: 2KBr + H2SO4 → K2SO4 + HBr The acid may be prepared by several other methods, as well, including reac-tion of bromine either with sulfur and water; or with phosphorus and water: 2Br2 + S + 2H2O → 4HBr + SO2 Hydrobromic acid also may be prepared by hydrogen exchange with a sodiumor potassium bromide solution when the solution is passed through a cation-exchange resin. Hydrobromic acid is stored and shipped in drums, tanks, carboys, or bot-tles, labeled as corrosive materials. The anhydrous gas is stored and shippedin cylinders under its vapor pressure.

合成方法白金触媒下で水素と臭素を反応させる

純化方法A solution of aqueous HBr ca 48% (w/w, constant boiling) is purified by distilling twice with a little red phosphorus, and the middle half of the distillate is taken. (The azeotrope at 760mm contains 47.8% (w/w) HBr.) [Hetzer et al. J Phys Chem 66 1423 1962]. Free bromine can be removed by Irvine and Wilson's method for HI (see above), except that the column is regenerated by washing with an ethanolic solution of aniline or styrene. Hydrobromic acid can also be purified by aerating with H2S, distilling and collecting the fraction boiling at 125-127o. [Heisig & Andur Inorg Synth I 155 1939.] HARMFUL VAPOURS.
