Product data sheet (Polymer production, 2021-9-17): Applications: TIBAL is used as a cocatalyst in the Ziegler-Natta polymerization of olefins. Storage: TIBAL and its solutions are stable when stored under a dry, inert atmos-phere and away from heat. TIBAL decomposes slowly above ~ 50°C to produce diisobutylaluminum hydride (DIBAL-H) and isobutylene. Further heating will result in decomposition of DIBAL-H to hydrogen, isobutylene and elemental aluminum. Packaging and transport: TIBAL and its solutions are available worldwide in cylinders and portable tanks. In North America only, TIBAL 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: TIBAL ignites upon exposure to air and reacts violently with water. Hydrocarbon solutions of TIBAL may also ignite upon exposure to air. TIBAL 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 TIBAL and its solutions are aluminum oxide, carbon dioxide and water. TIBAL causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling TIBAL. Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of TIBAL. This information should be thoroughly reviewed prior to acceptance of this product. The SDS is available at nouryon.com/sds-search. Additional information: Availability: TIBAL is a commercial product available as the neat pyrophoric liquid and as pyrophoric and non-pyrophoric solutions in a variety of hydrocarbon solvents.
