Metals, Organic Compounds

Colorless liquid; [Hawley]

Used as a polymerization catalyst; [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] Reacts violently with water, liberating extremely flammable gases; Spontaneously flammable in air; A corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Inhalation may result in laryngeal edema and chemical pneumonitis; [MSDSonline] HCl released when spilled in water; [ERG] 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irritants; [HSDB] Organic aluminum compounds can cause irritation or burns, depending upon concentration; [Ullmann] TLV withdrawn for aluminum alkyls because of inadequate toxicological data; [ACGIH] See "Aluminum."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."

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]

LC50 (rat) = 67 ppm
