  • Uses Triethylamine is a clear, colorless liquid with an Ammonia or fish-like odor. It is used in making waterproofing agents, and as a catalyst, corrosion inhibitor and propellant. It is mainly used as base, catalyst, solvent and raw material in organic synthesis and is generally abbreviated as Et3N, NEt3 or TEA. It can be used to prepare phosgene polycarbonate catalyst, polymerization inhibitor of tetrafluoroethylene, rubber vulcanization accelerator, special solvent in paint remover, enamel anti-hardener, surfactant, antiseptic, wetting agent, bactericides, ion exchange resins, dyes, fragrances, pharmaceuticals, high-energy fuels, and liquid rocket propellants, as a curing and hardening agent for polymers and for the desalination of seawater.

It acts as a catalyst in the formation of urethane foams and epoxy resins, dehydrohalogeantion reactions, acid neutralizers for condensation reactions and Swern oxidations. It finds application in reverse phase high-performance liquid chromatography (HPLC) as a mobile-phase modifier. It is also used as an accelerator activator for rubber, as a propellant, as a corrosion inhibitor, as a curing and hardening agent for polymers and for the desalination of seawater. Furthermore, it is used in the automotive casting industry and the textile industry.
  • Physical properties Clear, colorless to light yellow flammable liquid with a strong, penetrating, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were <400 μg/m3 (<100 ppbv) and 1.1 mg/m3 (270 ppbv), respectively (Hellman and Small, 1974). An odor threshold concentration of 0.032 ppbv was determined by a triangular odor bag method (Nagata and Takeuchi, 1990).
