Description générale

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.

Conditionnement

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:For instructions please refer to technical bulletin AL-136: The Aldrich Sure/Pac™ Cylinder System

Autres remarques

Storage below 20°C may cause crystallization.
