Product data sheet (Pharmaceutical industry, 2021-9-17): Applications: TMAL is used as a cocatalyst in the Ziegler-Natta polymerization of olefins. TMAL is also used in the production of compound semiconductors used in electronic devices. Storage: TMAL and its solutions are stable when stored under a dry, inert atmosphere and away from heat. CAUTION: Neat TMAL may undergo exothermic decomposition with gas evolution at elevated temperatures (see section on Safety & handling). Thermal decomposition products include methane and an amorphous solid containing > 50% aluminum. Packaging and transport: TMAL and its solutions are available worldwide in cylinders and portable tanks. In North America only, TMAL 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: TMAL ignites upon exposure to air and reacts violently with water. Hydrocarbon solutions of TMAL may also ignite upon exposure to air. TMAL 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. If heated above 120°C, TMAL will undergo exothermic decomposition with evolution of flammable gas. Products of complete combustion of TMAL and its solutions are aluminum oxide, carbon dioxide and water. TMAL causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling TMAL. Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of TMAL. This information should be thoroughly reviewed prior to acceptance of this product. The SDS is available at nouryon.com/sds-search. Additional information: Availability: TMAL is a commercial product available as the neat pyrophoric liquid and as pyrophoric and non-pyrophoric solutions in a variety of hydrocarbon solvents. Consult your Nouryon representative for further information.
