Product data sheet (Pharmaceutical industry, 2021-9-17): Applications: DIBAL-H is used as a cocatalyst in the Ziegler-Natta polymerization of olefins and as a reducing agent in organic synthesis. Storage: DIBAL-H and its solutions are stable when stored under a dry, inert atmosphere and away from heat. DIBAL-H decomposes slowly above about 120°C. Decomposition products include hydrogen, isobutylene and elemental aluminum. Packaging and transport: DIBAL-H and its solutions are available worldwide in cylinders and portable tanks. In North America only, DIBAL-H 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: DIBAL-H ignites upon exposure to air and reacts violently with water. Hydrocarbon solutions of DIBAL-H may also ignite upon exposure to air. Solutions of DIBAL-H in ethers have been known to decompose violently. DIBAL-H 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 DIBAL-H and its solutions are aluminum oxide, carbon dioxide and water. DIBAL-H causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling DIBAL-H. Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of DIBAL-H. This information should be thoroughly reviewed prior to acceptance of this product. The SDS is available at nouryon.com/sds-search. Additional information: Availability: DIBAL-H is a commercial product 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.
