Overview
Triethylaluminum is a critical organometallic catalyst produced via the direct reaction of aluminum with ethyl chloride. Its molecular formula is C6H15Al (CAS: 97-93-8). This pyrophoric liquid serves as an essential co-catalyst in Ziegler-Natta polymerization processes.
Application
- Polyolefin production for high-density polyethylene (HDPE).
- Manufacturing of linear low-density polyethylene (LLDPE).
- Synthesis of specialized elastomers and copolymers.
Precautions
- Strictly store under inert atmosphere to prevent spontaneous ignition.
- Mandatory use of fire-resistant protective gear during handling.
- Not suitable for clinical or pharmaceutical direct applications.
