Description

Triethylaluminum is a highly reactive organoaluminum compound primarily used as a catalyst and alkylating agent in industrial chemistry. Its pyrophoric nature and strong Lewis acidity make it indispensable for initiating and controlling critical polymerization reactions. This chemical is essential for manufacturers in the polymer, specialty chemical, and pharmaceutical intermediate sectors seeking to produce high-performance materials with precise molecular structures.

Application

• Polymerization Catalyst: A key co-catalyst in Ziegler-Natta systems for the production of polyethylene and polypropylene.
• Olefin Production: Used in the synthesis of linear α-olefins via chain growth reactions.
• Organic Synthesis: Acts as a powerful alkylating and reducing agent in the synthesis of fine chemicals and pharmaceutical intermediates.
• Semiconductor Manufacturing: Employed as a precursor in Metal-Organic Chemical Vapor Deposition (MOCVD) for thin-film growth.
• Fuel Additive: Used in certain high-energy rocket propellants and pyrophoric fuels.
• Chemical Vapor Deposition (CVD): Serves as an aluminum source for depositing aluminum-containing films and coatings.

Quality Control

Our Triethylaluminum is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Production adheres to relevant ISO quality management standards, and all materials are handled in dedicated, moisture-free environments. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and process validation requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and pyrophoric nature, it must be stored under an inert atmosphere (nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, ignition sources, and incompatible materials such as oxidizers, acids, and water. Specific temperature recommendations are provided on the material safety data sheet.
