Triethylaluminium (TEA) is an organoaluminium compound, composed of a dimeric structure ( Al2Et6 ) which is bridged by a pair of ethyl groups and 2 five-coordinate carbon centres. In appearance TEA is a colourless volatile liquid which ignites immediately if exposed to air; which is why it is stored in stainless steel containers as a pure liquid or in the form of a solution as a hyrdrocarbon solvent such as heptanes.
Its efficient synthesis makes triethylaluminium one of the most available organoaluminium compounds. TEA can also be generated from ethylaluminium sesquichloride (Al2Cl3Et3), which arises by treating aluminium powder with chloroethane.
In terms of reactivity, triethylaluminium reacts violently with water to form a flammable ethane gas but at the same time has no significant reaction to commonly found materials.
Mainly used as a co-catalyst in the synthetic polymerization of HDPE and LLDPE, Triethylaluminium has been utilized in the industry as an intermediate in the production of fatty alcohols, which are later converted into detergents. As a co-catalyst it forms an essential part of the catalyst system used as activator to accelerate the reaction which produces a polymer. Its highly pyrophoric properties make it a great pyrophoric agent which is the reason for it being used as a rocket engine ignitor. Its high pyrophoricity also makes it ideal as a fuel to be used to power rockets but only as a mixture with triethylborane.

Tri-Ethyl Aluminium Price (TEAL) rebounded this quarter, backed by improved offtakes from the downstream sectors. The demand for Tri-Ethyl Aluminium Prices improved after resumed plant operations in US Gulf Coast. Several polymer plants resumed their operations to produce major polymers like LDPE and LLDPE during this quarter, which improved the offtakes for TEAL as a catalyst in the process. However, initially during April demand remained low, as manufacturers were analysing damages on their plants, which affectively improved week over week in the country.
