Description

Trioctadecylaluminium is a high-purity organoaluminium compound, specifically a trialkylaluminium, where the alkyl group is a long-chain octadecyl (C18) unit. This compound serves as a highly effective catalyst and stoichiometric reagent in advanced polymerization and organic synthesis processes. It is essential for industrial and research chemists requiring a long-chain alkylating agent or a co-catalyst for Ziegler-Natta type systems, particularly in the production of specialized polyolefins and high-value fine chemicals.

Application

• As a co-catalyst or activator in Ziegler-Natta and other transition metal catalyst systems for polyolefin production.
• As a stoichiometric alkylating agent in organic synthesis for the introduction of long-chain alkyl groups.
• As a key component in the synthesis of specialty polymers and elastomers with tailored properties.
• In the preparation of organometallic precursors for materials science and nanotechnology applications.
• For research and development of novel catalytic processes in both academic and industrial laboratories.
• In the synthesis of fine chemicals and pharmaceutical intermediates requiring selective alkylation.

Quality Control

Our Trioctadecylaluminium is manufactured under stringent controls to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a comprehensive suite of analytical techniques including NMR, titration, and GC analysis. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming key parameters such as assay, alkyl content, and impurity profiles to meet your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and moisture-sensitive nature, this material must be stored and handled under an inert atmosphere (argon or nitrogen). Store in a cool, dry, well-ventilated area away from heat, ignition sources, and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability.
