Aluminoxane
From Wikipedia, the free encyclopedia
Aluminoxane refers to compounds that are obtained by the partial hydrolysis of Trialkylaluminiums.

- TiBAO Triisobutylaluminoxane (hydrolysis of Triisobutylaluminium)
- MAO Methylaluminoxane (hydrolysis of Trimethylaluminium)
[edit] Synthesis
See the specific aluminoxane in the List of aluminoxanes (vide supra)
[edit] Uses
Aluminoxanes serve as activators for catalystic olefin polymerisation (see Ziegler-Natta catalyst).
They also serve a function as scavenger for impurities (e.g. water) in reactions that are sensitive to these impurities.
[edit] Safety
Hydrolysis of Trialkylaluminium compounds is a highly exothermic process, and the starting trialkylaluminium compounds are often pyrophoric or burn in contact with air.
