Triethylaluminium (TEAL) is an organoaluminium compound. Despite its name, the formula for this compound is Al₂(C₂H₅)₆, shortened to Al₂Et₆ (Et = ethyl). This volatile, colorless liquid is highly pyrophoric, igniting immediately upon exposure to air. It is normally stored in stainless steel containers either as a pure liquid or as a solution in hydrocarbon solvents such as hexane, heptane, or toluene. TEAL is mainly used as a co-catalyst in the industrial production of polyethylene and for the production of medium chain alcohols.
