Methyl aluminum sesquibromide
Aluminum, tribromotrimethyldi-; Methylaluminum sesquibromide; Tribromotrimethyldialuminum; [ChemIDplus] UN3051
Metals, Organic Compounds
Cloudy yellow liquid; [HSDB]
Used as catalyst for polymerization of olefins and hydrogenation of aromatics; [HSDB] Organic aluminum compounds are "some of the most important, highest volume, highest value organometallic compounds in production." [Ullmann]
Aluminum alkyl halides release large amounts of HCl when spilled in water; [ERG 2012] Produces hydrogen bromide when decomposes; [Sax] Reacts violently with water and air; Organoaluminum compounds are corrosive; Harmful if absorbed through the skin or inhaled; The butyl alkyls and below are pyrophoric; Aluminum alkyls are eye irritants; [HSDB] Organic aluminum compounds can cause irritation or burns, depending upon concentration; [Ullmann] TLV withdrawn for aluminum alkyls because of inadequate toxicological data; [ACGIH] See "Aluminum." See "ORGANOMETALS."
|Dangerous When Wet|
Yes - A material that, by contact with water, is liable to become spontaneously flammable or to give off flammable or toxic gas at a rate greater than 1 L per kilogram of the material, per hour; [ERG 2004]
