化学的特性Hydrogen iodide is a colourless to yellow/brown with an acrid odour non-flammable gas. Hydrogen iodide is incompatible with water and other halides. Hydrogen iodide, upon contact with moisture in air, releases dense vapours. Hydrogen iodide reacts with water to form corrosive acids and reacts violently with alkalis. Most metals corrode rapidly on contact with wet hydrogen iodide, and prolonged exposure of hydrogen iodide to fire or intense heat has been reported to cause the container to rupture and rocket.
物理的性質This is a strong acid, made by dissolving HI gas in water. However, hydrogen iodide and hydroiodic acid differ in that the former is a gas under standard conditions whereas the other is an aqueous solution of said gas. They are noninterconvertible. That is, once the acid is formed with water, it cannot be recovered like HCl or HBr. Hydroiodic acid is used in organic and inorganic synthesis as one of the primary sources of iodine and as a reducing agent.
With moist air, HI gas gives a mist (or fumes) of hydroiodic acid. It is exceptionally soluble in water. One liter of water will dissolve 425 L of HI, the final solution containing only four water molecules per molecule of HI. As stated, although chemically related, hydroiodic acid is not pure HI but a mixture containing it. Commercial “concentrated” hydroiodic acid usually contains 90–98% HI by mass.
使用Hydriodic acid is used in the manufactureof iodides, as a reducing agent, and indisinfectants and pharmaceuticals.
使用Reducing agent, manufacture of inorganic iodides, pharmaceuticals, disinfectants. The 57% acid is also used for analytical purposes, such as methoxyl determinations.
定義hydrogen iodide: A colourless gas,HI; m.p. –51°C; b.p. –35.38°C. It canbe made by direct combination ofthe elements using a platinum catalyst.It is a strong acid dissociating extensivelyin solution (hydroiodic acid or hydriodic acid). It is also a reducingagent.
一般的な説明A colorless to yellow liquid with a pungent odor. Consists of a solution of hydrogen iodide in water. Fumes irritate the eyes and mucous membranes. Corrosive to metals and to tissue.
It is prepared by the reaction of iodine and hydrosulfuric acid or by the reaction of phosphorus plus iodine plus water followed by distillation. Concentrated hydroiodic acid reacts with the oxygen of the air to form free iodine, which gives a brownish color to the solution. It also gives an idea of the reducing nature of this acid. It is an important reagent in organic chemistry and is used commercially in the preparation of iodides.
空気と水の反応Soluble in water with release of heat.
反応プロフィールHYDROIODIC ACID reacts exothermically with organic bases (amines, amides) and inorganic bases (oxides and hydroxides of metals). 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 [Lewis]. Mixtures with concentrated sulfuric acid can evolve toxic hydrogen iodide gas at a dangerous rate. Decomposes at high temperatures to emit toxic products. Reacts with fluorine, dinitrogen trioxide, nitrogen dioxide/dinitrogen tetraoxide, and fuming nitric acid.
危険性Strong irritant. Poison.
健康ハザードHydriodic acid is a corrosive liquid thatcan produce burns on contact with the skin.Contact of acid with the eyes can causesevere irritation. The gas, hydrogen iodide, isa strong irritant to the eyes, skin, and mucousmembranes. No exposure limit has been setfor this gas.
健康ハザードTOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
火災危険Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
純化方法Iodine can be removed from aqueous HI, probably as the amine hydrogen triiodide, by three successive extractions using a 4% solution of Amberlite LA-2 (a long-chain aliphatic amine) in CCl4, toluene or pet ether (10mL per 100mL of acid). [Davidson & Jameson Chem Ind (London) 1686 1963.] Extraction with tributyl phosphate in CHCl3 or other organic solvents is also suitable. Alternatively, a De-acidite FF anion-exchange resin column in the OH--form using 2M NaOH, then into its I--form by passing dilute KI solution through, can be used. Passage of an HI solution under CO2 through such a column removes polyiodide. The column can be regenerated with NaOH. [Irving & Wilson Chem Ind (London) 653 1964]. The earlier method was to reflux with red phosphorus and distil in a stream of N2. The colourless product is stored in ampoules in the dark [Bradbury J Am Chem Soc 74 2709 1952, Heisig & Frykholm Inorg Synth I 157 1939]. It fumes in moist air. HARMFUL VAPOURS.
