Product Application of TriethylamineCAS#121-44-8

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.
