| Chemical Properties | Back Directory | [Description]
Acetyl iodide is a colourless, fuming liquid with a pungent odour. It is soluble in benzene
and ether. Acetyl iodide is toxic, corrosive, and reacts with water or steam to produce toxic and corrosive fumes. The vapours of acetyl iodide are irritating to the eyes and mucous
membranes. Vapour causes pulmonary oedema. It is corrosive to metals and skin. Acetyl
iodide turns brown on exposure to air as it reacts exothermically with moisture in the air
to give hydrogen iodide (hydroiodic acid), a strong irritant. It decomposes in water to give
acidic products. Inhalation, ingestion, or contact of the skin and the eyes with vapours, dusts,
or substance may cause severe injury, burns, or death. Contact with molten form of acetyl
iodide causes severe burns to skin and eyes. Reaction with water or moist air will release
toxic, corrosive, or flammable gases. Reaction with water may generate much heat that will
increase the concentration of fumes in the air. Fire will produce irritating, corrosive, and/
or toxic gases. Run-off from fire control or dilution water may be corrosive and/or toxic and
cause pollution. | [Boiling point ]

A toxic, corrosive material. Reacts with water or steam to produce toxic and corrosive fumes. Dangerous to use. When heated to decomposition it emits toxic fumes of I-. See also IODIDES. |
| Hazard Information | Back Directory | [General Description]
A colorless, fuming liquid with a pungent odor. Soluble in benzene and ether (Merck 11th ed., 1989). Vapors are irritating to the eyes and mucous membranes. Vapor causes pulmonary edema. Corrosive to metals and skin. | [Reactivity Profile]
ACETYL IODIDE decomposes exothermically in water or alcohol. Reacts vigorously and exothermically with bases. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. | [Air & Water Reactions]
Turns brown on exposure to air as ACETYL IODIDE(507-02-8) reacts exothermically with moisture in the air to give hydrogen Iodide (hydroiodic acid), a strong irritant. Decomposes in water to give acidic products. | [Health Hazard]
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Fire Hazard]
Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | [Purification Methods]
Purify it by fractional distillation. [Beilstein 2 H 174, 2 I 80, 2 II 177, 2 III 393, 2 IV 399.] TOXIC and LACHRYMATORY. |
