  • 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.
  • 化学的特性 colourless liquid with a strong irritating odour
  • 物理的性質 Colorless gas; fumes in moist air; pungent acrid odor; nonflammable; heav-ier than air; density 2.71 (air=1.0); gas density 3.55 g/L at 25°C; liquefies at-66.4°C; solidifies at -86.8°C; critical temperature 89.8°C; critical pressure84.5 atm; highly soluble in water (saturated aqueous solution contains 66%HBr at 25°C); forms a constant-boiling azeotrope at 47.5% HBr in solution,boiling at 126°C at atmospheric pressure; soluble in alcohol; a 0.10Maqueoussolution is 93% ionized to H+and Br ? ions at 18°C.
  • 使用 Hydrobromic acid is used in the manufacture of bromide, as an alkylation catalyst, and in organic synthesis.
  • 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.
  • 使用 The Concentrated acid is used principally in analytical chemistry and organic preparations.
  • 定義 Hydrogen bromide in aqueous solution.
  • 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.
  • 定義 A colorless liquid produced by adding hydrogen bromide to water. It shows the typical properties of a strong acid and it is a strong reducing agent. A convenient way of producing hydrobromic acid is to bubble hydrogen sulfide through bromine water. Although it is not as strong as hydrochloric acid it dissociates extensively in water and is a good proton donor.
  • 定義 hydrogen bromide: A colourlessgas, HBr; m.p. –88.5°C; b.p. –67°C. Itcan be made by direct combinationof the elements using a platinum catalyst.It is a strong acid dissociatingextensively in solution (hydrobromicacid).
  • 空気と水の反応 Acrid odor, fumes in moist air forming clouds containing hydrobromic acid. Heat of solution large, [Merck, 11th ed., 1989].
  • 反応プロフィール HYDROGEN BROMIDE is an anhydrous (no water) strong acid. Reacts rapidly and exothermically with bases of all kinds (including amines and amides). Reacts exothermically with carbonates (including limestone and building materials containing limestone) and hydrogen carbonates to generate carbon dioxide. Reacts with sulfides, carbides, borides, and phosphides to generate toxic or flammable gases. Reacts with many metals (including aluminum, zinc, calcium, magnesium, iron, tin and all of the alkali metals) to generate flammable hydrogen gas. Reacts violently with acetic anhydride, 2-aminoethanol, ammonium hydroxide, calcium phosphide, chlorosulfonic acid, 1,1-difluoroethylene, ethylenediamine, ethyleneimine, oleum, perchloric acid, b-propiolactone, propylene oxide, silver perchlorate/carbon tetrachloride mixture, sodium hydroxide, uranium(IV) phosphide, vinyl acetate, calcium carbide, rubidium carbide, cesium acetylide, rubidium acetylide, magnesium boride, mercury(II) sulfate, calcium phosphide, calcium carbide.
  • 危険性 Toxic by inhalation, strong irritant to eyes and skin.
  • 健康ハザード Hydrobromic acid is a corrosive liquid. Thegas is a strong irritant to the eyes, nose, andmucous membranes. In humans, exposure to5 ppm for a few minutes can cause irritationof the nose. Irritation of the eyes and lungsmay be felt at higher concentrations. Thedetectable odor threshold is 2 ppm.
  • 健康ハザード Hydrobromic acid and hydrogen bromide gas are highly corrosive substances that can cause severe burns upon contact with all body tissues. The aqueous acid and gas are strong eye irritants and lacrimators. Contact of concentrated hydrobromic acid or concentrated HBr vapor with the eyes may cause severe injury, resulting in permanent impairment of vision and possible blindness. Skin contact with the acid or HBr gas can produce severe burns. Ingestion can lead to severe burns of the mouth, throat, and gastrointestinal system and can be fatal. Inhalation of hydrogen bromide gas can cause extreme irritation and injury to the upper respiratory tract and lungs, and exposure to high concentrations may cause death. HBr gas is regarded as having adequate warning properties.
    Hydrogen bromide has not been found to be carcinogenic or to show reproductive or developmental toxicity in humans.
  • 火災危険 Behavior in Fire: Pressurized container may explode and release toxic, irritating vapor.
  • 燃焼性と爆発性 Noncombustible, but contact with metals may produce highly flammable hydrogen gas.
  • 材料の用途 Hydrogen bromide does not aggressively attack common metals of construction while in the anhydrous state. However, in the presence of moisture, hydrogen bromide will attack most metals except platinum and silver. Galvanized pipe, brass, and bronze should be avoided. Steel, Monel, and aluminum-silicon-bronze have proven satisfactory in anhydrous hydrogen bromide service.
  • Physiological effects Hydrogen bromide is extremely irritating to the eyes, mucous membranes of the respiratory tract, and skin. Contact may cause bums. Repeated short exposures to concentrations of about 35 ppm can cause irritation to the nose and throat with mucous production and indigestion. Inhalation of higher concentrations can cause pulmonary edema and laryngeal spasm, and can be fatal. Skin contact with the vapor or liquid causes severe tissue irritation and necrosis [2].
  • 貯蔵 Splash goggles and rubber gloves should be worn when handling this acid, and containers of HBr should be stored in a wellventilated location separated from incompatible metals. Water should never be added to HBr because splattering may result; always add acid to water. Containers of hydrobromic acid should be stored in secondary plastic trays to avoid corrosion of metal storage shelves due to drips or spills.
    Cylinders of hydrogen bromide should be stored in cool, dry locations, separated from alkali metals and other incompatible substances.
  • 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.
  • 不和合性 Hydrobromic acid and hydrogen bromide react violently with many metals with the generation of highly flammable hydrogen gas, which may explode. Reaction with oxidizers such as permanganates, chlorates, chlorites, and hypochlorites may produce chlorine or bromine.
  • 廃棄物の処理 In many localities, hydrobromic acid or the residue from a spill may be disposed of down the drain after appropriate dilution and neutralization. Otherwise, hydrobromic acid and waste material containing this substance should be placed in an appropriate container, clearly labeled, and handled according to your institution's waste disposal guidelines. Excess hydrogen bromide in cylinders should be returned to the manufacturer. For more information on disposal procedures, see Chapter 7 of this volume.
  • GRADES AVAILABLE Hydrogen bromide is typically available in 99.8 percent purity.
    Gas purity guidelines have been developed and published by Semiconductor Equipment and Materials International and can be found in the Book of SEMI Standards, Gases Volume.
