Ultra-Low Hydride Triethylaluminum (ULH-TEA) - 97-93-8

Ultra-Low Hydride Triethylaluminum (ULH-TEA)

(C2H5)3Al

CAS Number:  97-93-8 EC Number:  202-619-3

Ultra-low hydride triethylaluminum (ULH-TEA) is used primarily as a catalyst component in Ziegler-Natta type systems for olefin and diene polymerizations. It is also used in ethylene oligomerization to produce olefins and, in chain growth of ethylene, to produce longer chain aluminum alkyls, which are then converted to primary alcohols or other products.

Handling Instructions

The pyrophoric nature of ULH-TEA presents potential hazards not common to most liquid chemicals used by industry in tank truck quantities. ULHTEA, being pyrophoric, breaks into flame spontaneously and gives off dense smoke when exposed to air. It reacts violently with water. ULH-TEA is a clear, noncorrosive mobile liquid with a low vapor pressure. Hydrocarbon solutions of ULH-TEA, depending on the concentration and temperature, may not be pyrophoric. However, these solutions must still be blanketed with an inert gas such as dry nitrogen because ULH-TEA 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.
