Tri-N-Hexylaluminum (TNHA)
(n-C6H13)3Al
Tri-n-hexylaluminum (TNHA) can be used as a component of Ziegler-Natta catalysts for olefin and diene polymerizations. It may also be used to alkylate other metals or as an alkylating agent in organic syntheses. Certain transition metal salts may be reduced by tri-n-hexylaluminum.
Handling Instructions
The pyrophoric nature of TNHA presents potential hazards not common to most liquid chemicals used by industry in tank truck quantities. TNHA, being pyrophoric, breaks into flame spontaneously and gives off dense smoke when exposed to air. It reacts violently with water. TNHA is a clear, noncorrosive mobile liquid with a low vapor pressure. Hydrocarbon solutions of TNHA, depending on the concentration and temperature, may not be pyrophoric. However, these solutions still must be blanketed with an inert gas such as dry nitrogen because TNHA will react with air and moisture at the surface of the solution, giving off dense smoke, heat and flammable gas. For specific information on the safe handling and toxicity of this product, please refer to the Material Safety Data Sheet, which is available upon request.
