SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen bromide and carbonyl bromide. Reacts violently with water, methanol and ethanol. This produces hydrogen bromide. Attacks many metals in the presence of water.
Chemical stability
Turns yellow in air
Possibility of hazardous reactions
Flammable hydrogen gas may collect in spaces.The vapour is heavier than air.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].
Conditions to avoid
no data available
Incompatible materials
Reacts violently with protic organic solvents ... and the aprotic solvents, dimethylformamide and dimethyl sulfoxide. Reaction with ethers is also potentially hazardous. Acyl halides
Hazardous decomposition products
When heated to decomp, it emits highly corrosive and toxic fumes of carbonyl bromide and bromine. ...

Persistence and degradability
no data available
Bioaccumulative potential
Acetyl bromide will decompose violently in water(1). Because of its short half-life in water, bioconcentration of acetyl bromide in aquatic organisms is very unlikely(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for acetyl bromide can be estimated to be 2(SRC). According to a classification scheme(2), this estimated Koc value suggests that acetyl bromide is expected to have very high mobility in soil. However, in view of its violent decomposition in the presence of water(3) and the 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(4), it is unlikely that acetyl bromide would persist for long in moist soils(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
Reacts violently with fire extinguishing agents such as water.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
