TEAL (Triethylaluminum)

About this product

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 α-olefins and α-alcohols and as an alkylating agent in the production of other organometallic compounds and organic intermediates.

Product data sheet (Pharmaceutical industry, 2021-9-17): Applications: 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 α-olefins and α-alcohols and as an alkylating agent in the production of other organometallic compounds and organic intermediates. Storage: TEAL and its solutions are stable when stored under a dry, inert atmosphere and away from heat. TEAL decomposes slowly above 120°C. Thermal decomposition products include hydrogen, ethylene and elemental aluminum. Packaging and transport: TEAL and its solutions are packed in cylinders and portable tanks. In North America, TEAL is also available in tank trailers and rail cars. Containers are fabricated from carbon steel and are equipped with dip tubes for top discharge and all connections are located in the vapor space. Both packaging and transport meet the international regulations. Safety and handling: TEAL ignites upon exposure to air and reacts violently with water. Hydrocarbon solutions of TEAL may also ignite upon exposure to air. TEAL and its solutions must be handled under a dry, inert atmosphere, e. g. nitrogen or argon. Water must be scrupulously removed from process equipment prior to putting it into metal alkyls service. Failure to do so may result in an explosion. Products of complete combustion of TEAL and its solutions are aluminum oxide, carbon dioxide and water. TEAL causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling TEAL. Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of TEAL. This information should be thoroughly reviewed prior to acceptance of this product. The SDS is available at nouryon.com/sds-search. Additional information: Availability: TEAL is available as the neat pyrophoric liquid and as pyrophoric and nonpyrophoric solutions in a variety of hydrocarbon solvents. Consult your Nouryon representative for further information.
