General description
Trimethylaluminum ismainly used in the industrial production of polyethylene and other syntheticpolymers, where it is used as a co-catalyst for the polymerization reaction. Itis also used as a precursor to produce inorganic aluminum compounds, includingalumina and various zeolites.
Application
Trimethylaluminum can be used as:
- A chemical vapor deposition precursor to fabricate PbSe quantum dot solids for optoelectronic devices.
- An aluminum precursor for the flame synthesis of alumina nanofibers.
- A reagent for efficient synthesis of allenes.
