Beschreibung

‘Iodine’ is derived from iodes, a Greek word meaning violet. It is a member of the halide family and hydrogen iodide is considered a strong acid.

Chemische Eigenschaften

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.

Physikalische Eigenschaften

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.

Verwenden

Hydriodic acid is used in the manufactureof iodides, as a reducing agent, and indisinfectants and pharmaceuticals.

Verwenden

Reducing agent, manufacture of inorganic iodides, pharmaceuticals, disinfectants. The 57% acid is also used for analytical purposes, such as methoxyl determinations.

Verwenden

Hydriodic acid (HI) is a colorless solution formed when hydrogen iodide gas is dissolved in water, commercially of strength 10% HI, frequently colored brown by iodine. There is a maximum constant boiling point 127 °C (774 mm) at 57% HI (distillate) for mixtures of hydriodic acid and water. Hydriodic acid is used in the preparation of iodides, and as an important reagent in organic chemistry.

Definition

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.

synthetische

Hydrogen iodide is prepared by direct combination of hydrogen and iodinevapor in the presence of platinum catalyst:
H2 + I2 → 2HI
The compound is produced in commercial scale by reaction of iodine withhydrazine or hydrogen sulfide:
2I2 + N2H4 → 4HI + N2
I2 + H2S → 2HI + S
Hydriodic acid may be prepared by dissolving hydrogen iodide gas in water.The acid also may be obtained by electrolysis of iodine solution or by passinghydrogen sulfide into a suspension of iodine in water and boiling to expelexcess sulfide. After boiling, the precipitated sulfur is removed by filtrationthrough fritted glass plate or glass wool.
Hydriodic acid in small quantities may be prepared by adding water care-fully to a solid mixture of red phosphorus and iodine.
Technical grade hydriodic acid is a 47% HI solution and usually has abrown color due to the presence of free iodine, produced by air oxidation of HI.Hydriodic acid should be stored in the dark to prevent photochemical decom-position, and free from air to prevent oxidation. The addition of 1.5%hypophosphorus acid (H3PO2) prevents oxidative decomposition.
Hydriodic acid also is commercially sold at 57% (azeotropic concentration)and 10% aqueous solutions.

Allgemeine Beschreibung

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.

Air & Water Reaktionen

Soluble in water with release of heat.

Reaktivität anzeigen

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.

Hazard

Strong irritant. Poison.

Health Hazard

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.

Health Hazard

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.

Brandgefahr

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.

läuterung methode

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.

Toxicity evaluation

Hydroiodic acid is a strong irritant. When used as an expectorant, hydroiodic acid is believed to act by irritating the gastric mucosa, which then stimulates respiratory tract secretion.
