General description
Trimethylaluminum (TMA) is the most reactive and volatile among all organoaluminium compounds. It is extremely pyrophoric. It acts as a highly reactive reducing and alkylating agent.
Application
TMA is used in a Ziegler Natta catalyst for polymerization and hydrogenation. TMA is mainly used for the production of methylaluminoxane, such as metalorganic chemical vapor deposition (MOCVD) of:
- Al2O3 using TMA and O2 precursors.
- Al4C3 layers have been grown on Al2O3 (0001) using TMA and methane as source materials for aluminum and carbon.
Packaging
Supplied in a Sure/Pac™ cylinder with a 1/4-turn bronze ball valve (Z122661) installed. This has a female 1/4"" NPT outlet thread and is closed with a male 1/4"" NPT carbon steel plug. The plug must be removed before use after ensuring the valve is in the closed position.
Compatible with the following:
- Aldrich® Sure/Pac™ station for liquefied gases Z566446
- PTFE Sealing tape Z104388 or Z221880
- Straight septum-inlet adapter Z118141 with septa Z565687 or Z565695
Other Notes
Storage below 20°C may cause crystallization.
