              Availability

              TNHAL is a commercial product available as the neat pyrophoric liquid and as pyrophoric and nonpyrophoric solutions in a variety of hydrocarbon solvents.

              Storage

              TNHAL and its solutions are stable when stored under a dry,inert
              atmosphere and away from heat. TNHAL decomposes slowly above ~100C
              Decomposition products include hydrogen,hexene-1 and
              elementaI aluminum.

              Packaging and
              transport

              TNHAL and its solutions are available in cylinders and portable tanks
              In North America only. TNHAL 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

              TNHAL may ignite upon exposure to air and reacts violently with water.
              TNHAL 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.Products of complete
              combustion of TNHAL and its solutions are aIuminum oxide.carbon
              dioxide and water.TNHAL causes burns to the skin and eyes.It is
              imperative that proper personal protective equipment be worn when
              handling TNHAL.
              Please refer to the Material Safety Data Sheet(MSDS)for further
              information on the safe storage,use and handling of TNHAL.This
              information should be thoroughly reviewed prior to acceptance of this
              product.

              Applications

              TNHAL is used as a cocatalyst in the Ziegler-Natta polymerization of olefins
