Sources/Uses
Used as a polymerization catalyst and chemical intermediate; [Hawley] Organic aluminum compounds are "some of the most important, highest volume, highest value organometallic compounds in production." [Ullmann]
Comments
Aluminum alkyl halides release large amounts of HCl when spilled in water; [ERG 2016] May cause first degree burns after short exposure and second degree burns after longer contact; [CHRIS] Hazardous decomposition products include flammable vapors, HCl, AlCl3, and aluminum containing dust; Can cause thermal burns upon contact with eyes or skin and pulmonary edema after inhalation; [CHEMINFO MSDS] 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irritants; [HSDB] Organic aluminum compounds can cause irritation or burns, depending upon concentration; [Ullmann] TLV withdrawn for aluminum alkyls because of inadequate toxicological data; [ACGIH] See "Aluminum."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."
