Product data sheet (Polymer production, 2021-9-17): Applications: DIBAC is used as a cocatalyst in the Ziegler-Natta polymerization of olefins. Storage: DIBAC and its solutions are stable when stored under a dry, inert atmosphere and away from heat. DIBAC slowly decomposes at temperatures above ~ 165°C. Packaging and transport: DIBAC and its solutions are available worldwide in cylinders and portable tanks. In North America only, DIBAC 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: DIBAC ignites upon exposure to air and reacts violently with water. Hydrocarbon solutions of DIBAC may also ignite upon exposure to air. DIBAC 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 DIBAC and its solutions are aluminum oxide, carbon dioxide, hydrogen chloride and water. DIBAC causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling DIBAC. Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of DIBAC. This information should be thoroughly reviewed prior to acceptance of this product. The MSDS is available at nouryon.com/sds-search. Additional information: DIBAC 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.
