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.
