A colorless transparent liquid at normal temperature and pressure. With water, ammonia, ethanol, hydrogen chloride reaction. Soluble in ethane, heptane and other aliphatic saturated hydrocarbons and toluene, dimethyl benzene and other aromatic hydrocarbons. Triethylaluminum is stable at room temperature. At temperatures above 100 °c, substantial decomposition began. Sensitive to oxygen, spontaneous combustion in the air, and sometimes explosion. Explosive decomposition occurs in water, and combustion.
The crude triethylaluminum is reacted with water in tetrahydrofuran solution, and then subjected to rectification treatment to obtain high-purity triethylaluminum.
It is used as a raw material for MOCVD process and is used for depositing aluminum film in the production of diodes, transistors and integrated circuits. Used as a dopant in the fabrication of semiconductors. It is also an excellent catalyst for the polymerization of olefins.
no toxicity data have been reported in the literature. It is attached to the skin can damage tissue, the staff should be fully protected. Store in a cool and ventilated place, away from fire and heat sources. The workplace must have fire extinguishing facilities such as fire-resistant asbestos covers, carbon dioxide fire retardants, dry powder fire extinguishing agents, etc., but no use of water, carbon tetrachloride or bromochloromethane fire extinguishing agents.
