Useful:

• Uses: Catalyst intermediate for polymerization of olefins, especially ethylene; pyrophoric fuels; production of α-olefins and long-chain alcohols; gas plating of aluminum. Triethylaluminum, in combination withmany transition metal complexes, is used as Ziegler-Natta polymerization and hydrogenationcatalyst. Also, it is used as intermediatein organic syntheses. Triethylaluminum is used as a co-catalyst in the industrial production of polyethylene and for the production of medium chain alcohols. Used as a catalyst in Ziegler-Natta polymerization process for vinyl, olefin, diene polymerizations and linear oligomerization and cyclization of unsaturated hydrocarbons. It is also used as a catalyst to produce ethylene gas, chain growth of ethylene, longer chain aluminum alkyls, and in plating aluminum.
