Physicochemical Properties

Colorless liquid. Miscible with saturated hydrocarbons. The aluminum alkyls are highly flammable and reactive, colorless to yellow liquids at room temperature. The lighter trialkylaluminums ignite spontaneously in air. They are normally supplied and used in a 20% solution with a hydrocarbon solvent, such as hexane, heptane, benzene, toluene. Properties may depend on solvent. Reacts violently with water.

Applications and Usages

TEAL is used as a cocatalyst in the Ziegler-Natta polymerization of olefins. TEAL is also used in the Ziegler growth reaction for the production of -olefins and -alcohols and as an alkylating agent in the production of other organometallic  compounds and organic intermediates.
