Triethylamine CAS#121-44-8
Triethylamine (formula: C6H15N), also known as N, N-diethylethanamine, is the most simple tri-substituted uniformly tertiary amine, having typical properties of tertiary amines, including salifying, oxidation, Hing Myers test (Hisberg reaction) for triethylamine does not respond. It is colorless to pale yellow transparent liquid, with a strong smell of ammonia, slightly fuming in the air. Boiling point: 89.5 ℃, relative density (water = 1): 0.70, the relative density (Air = 1): 3.48, slightly soluble in water, soluble in alcohol, ether. Aqueous solution is alkaline, flammable. Vapor and air can form explosive mixtures, the explosion limit is 1.2% to 8.0%. It is toxic, with a strong irritant.

Product Application Of Triethylamine CAS#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.
