Description
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.

Triethylaluminum Use and Manufacturing
It can be used for the preparation of tertiary alcohols, secondary alcohols and polyolefin catalysts, and can also be used as a raw material for the preparation of other metal organic compounds and aluminum plating. The pure product can be used in metal organic chemical vapor deposition (MOCVD) process and can be used as rocket fuel.
