Fumes in air. Reacts violently with water producing heat and acidic fumes [Haz. Chem. Data. 1966]. Acetyl bromide reacts vigorously with water to generate gaseous HBr. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Bromide gas will be created in 0.08 minutes.

Acyl Halides, Sulfonyl Halides, and Chloroformates

Water-Reactive

ACETYL BROMIDE decomposes violently upon contact with water, steam, methanol or ethanol to form hydrogen bromide gas and acetic acid. Reacts vigorously with bases, both organic and inorganic. Incompatible with oxidizing agents and alcohols. Produces highly toxic fumes of bromine and carbonyl bromide when heated to decomposition [Sax, 9th ed., 1996, p. 34]. Vapor forms an explosive mixture with air [Kirk-Othmer, 3rd ed., Vol. 1, 1978, p. 162]. 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].

The vapour is heavier than air.

Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. A vapor-suppressing foam may be used to reduce vapors. FOR CHLOROSILANES, use AFFF alcohol-resistant medium-expansion foam to reduce vapors.

moderately toxic

IDENTIFICATION AND USE: Acetyl bromide is a colorless fuming liquid. It is used in organic synthesis and dye manufacture. HUMAN STUDIES: It could cause severe ocular damage if splashed in eye. However, in one instance of corneal burn, recovery is reported to have been complete in 48 hr. ANIMAL STUDIES: There are no data available.

LD50 Mouse ip 250 mg/kg

Acetyl bromide's production and use in organic synthesis and dye manufacture(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that acetyl bromide is expected to have very high mobility in soil(SRC). In view of its violent decomposition in the presence of water(3) and the high reactivity of structurally-similar compounds with active hydrogen groups which occur in soil(4), it is unlikely that acetyl bromide would persist for long in moist soils(SRC). Acetyl bromide is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 122 mm Hg at 25 °C(5). Biodegradation data in soil were not available(SRC, 2018).|AQUATIC FATE: Acetyl bromide decomposes violently in the presence of water(1) and, therefore, will not persist in the aquatic environment(SRC). Adsorption to sediment, volatilization, bioconcentration in aquatic species or biodegradation are not expected because of the very short lifetime of this compound in water(SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), acetyl bromide, which has a vapor pressure of 122 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase acetyl bromide may be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 5 years(SRC), calculated from its rate constant of 9.1X10-15 cu cm/molecule-sec at 25 deg(SRC) determined using a structure estimation method(3). Acetyl bromide contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).

Acetyl bromide decomposes violently with water and alcohol(1). It will, therefore, not persist for any length of time in an environment where water is present. The rate constant for the vapor-phase reaction of acetyl bromide with photochemically-produced hydroxyl radicals has been estimated as 9.1X10-15 cu cm/molecule-sec at 25 °C(2). This corresponds to an atmospheric half-life of about 5 years at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(SRC). Acetyl bromide contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).

Acetyl bromide will decompose violently in water(1). Because of its short half-life in water, bioconcentration of acetyl bromide in aquatic organisms is not an important evironmental fate process(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of acetyl bromide can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that acetyl bromide is expected to have very high mobility in soil(SRC). However, acetyl bromide will decompose violently in the presence of water(3). High reactivity of structurally-similar compounds such as acetyl chloride towards molecules with active hydrogen groups such as natural products containing amine, phenol, and alcohol functional groups that occur in soil has been reported(4). Therefore, it is unlikely that acetyl bromide would persist for long in moist soils(SRC).

Acetyl bromide will decompose violently in water(1) forming gaseous hydrogen bromide(2), preempting volatilization from water or soil surfaces as an environmental fate process(SRC). For the same reason, volatilization from moist soil surfaces is very unlikely(SRC). The potential for volatilization of acetyl bromide from dry soil surfaces may exist(SRC) based upon a vapor pressure of 122 mm Hg(3).

Occupational exposure to acetyl bromide may occur through inhalation and dermal contact with this compound at workplaces where acetyl bromide is produced or used. The general public is not expected to be exposed to acetyl bromide. (SRC)|Eye and skin contact, inhalation and ingestion.

Inhalation produces primary irritation of the respiratory tract; symptoms of lung damage may be delayed. Contact with liquid produces primary irritation of eyes and severe skin damage; delayed blistering is not uncommon. INGESTION: Sore throat, abdominal pain, and vomiting. (USCG, 1999)

INHALATION: remove victim from exposure; if breathing has stopped, give artificial respiration; if breathing is difficult, give oxygen; watch for delayed lung damage. EYES: flush with water for at least 15 min.; get medical attention. SKIN: flush with soap and water; treat burns as needed. (USCG, 1999)

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic acids and related compounds/|Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary.
