Chemical Properties
It is alkaline and forms soluble salts with inorganic acids. Flammable, its vapor can form explosive mixtures with air. It may cause combustion or explosion upon contact with open flames or high heat. Reacts strongly with oxidizing agents. Its vapor is heavier than air and can spread to lower areas over considerable distances, igniting upon contact with a fire source. It is corrosive.
Functions and Uses
In the organic synthesis industry, it can be used as a solvent, catalyst, and raw material. It is used to produce catalysts for the photochemical production of polycarbonate, polymerization inhibitors for tetrafluoroethylene, rubber vulcanization accelerators, special solvents in paint removers, enamel anti-hardening agents, surfactants, preservatives, bactericides, ion exchange resins, dyes, fragrances, pharmaceuticals, high-energy fuels, etc. In the pharmaceutical industry, triethylamine is consumed in products such as ampicillin sodium, amoxicillin, cefalexin, cefazolin sodium, cefradine, piperacillin, ketoconazole, vitamin B6, enoxacin, praziquantel, thiotepa, penicillamine, berberine hydrochloride, verapamil, and pipemidic acid.
Used as a catalyst in the photochemical production of polycarbonate, as a catalyst or solvent and raw material in organic synthesis, preservative, bactericide, pharmaceutical products, high-energy fuels, etc.
