Uses of TEA
It is used for the manufacture of pharmaceuticals, pesticides, polymerization inhibitors, high-energy fuel, rubber vulcanization agent, etc.
It can be used as solvents, catalysts and raw materials in organic synthesis industry. It can be used as catalyst for producing polycarbonate by phosgene, tetrafluoroethylene polymerization inhibitor, rubber vulcanization accelerator, the special solvent for paint remover, enamel anti-hardening agents, surface active agents, preservatives, bactericides, ionic exchange resins, dyes, perfumes, pharmaceuticals, the high-energy fuel and liquid rocket propellants, etc. The products consuming triethylamine in pharmaceutical industry (consumption of fixed, t/t): ampicillin sodium (0.465), amoxicillin (0.391), Pioneer Ⅳ (2.550), cefazolin sodium (2.442), Cefradine (1.093), piperacillin (0.584), ketoconazole (8.00), vitamin B6 (0.502), enoxacin (10.00), praziquantel (0.667), thiotepa (1.970), penicillamine ( 1.290), berberine (0.030), verapamil (0.540), alprazolam (3.950), o-chloro-phenylacetic acid (0.010) and PPA, etc.
It is used in the preparation of fourth amine compounds and synthesis catalyst, also used as solvents, rubber vulcanization accelerator, penetrant and waterproof agent.
Used as a solvent, overcast polymerization inhibitors, preservatives, and synthetic dyes, etc.
It is used for Producing quaternary ammonium compounds, synthesis catalyst, and used as rubber vulcanization accelerator, the solvent for the photographic industry. Mobile phase modifier is used in Reversed-Phase High Performance Liquid Chromatography (RP-HPLC) for separation of acidic, basic and neutral drugs. It can Improve the separation of amino acids and amino acid amide by inhibiting smearing.
Basic info of Triethylamine (TEA)
CAS NO: 121-44-8
Hazard category: flashpoint primary flammable liquid in class 3.2
Appearance and properties: Triethylamine (TEA) is a light yellow oily liquid with a strong ammonia odor.
Melting point (°C): -114.8
Relative density (the density of water= 1): 0.726
Boiling Point (°C): 89.5
TEA, an organic compound, named N,N-diethylethanamineunder the International Union of Pure and Applied Chemistry (IUPAC), is a colorless, transparent liquid with a strong ammonia odor, and slightly fumes in the air. It is slightly soluble in water and soluble in alcohol and ether. Its aqueous solution is slightly alkaline. TEA is a flammable, explosive, poisonous chemical and strong irritant. It is mainly used as a solvent, a curing agent, a catalyst, a polymerization inhibitor, a preservative, and a synthetic dye in the industry.
TEA is alkaline, reacting with inorganic acids to produce soluble salts. It is flammable and its vapor mixed with air can form an explosive mixture which explodes when exposed to fire or high heat energy. It can react with oxidants. Its vapor is heavier than air, thus it can spread to relatively far places at a lower level. When it encounters fire, it will fuel combustion. What's more, it is a corrosive substance.
TEA can be used as a solvent, catalyst and raw material in the organic synthesis industry. It can be used to prepare the phosgene polycarbonate catalyst, tetrafluoroethylene polymerization inhibitor, rubber vulcanization accelerator, and special solvent for paint removers. It is applied in the enamel anti-hardener, surfactant, antiseptic, bactericide, ion exchange resins, dyes, fragrances, pharmaceuticals, high-energy fuels, and liquid rocket propellants.
Skin contact: One should immediately remove contaminated clothing, flush skin with plenty of running water for at least 15 minutes, and seek medical advice.
Eye contact: One should immediately lift his lids and rinse thoroughly with plenty of running water or saline for at least 15 minutes, and seek medical advice.
Inhalation: One should withdraw quickly from the scene to an area filled with fresh air. Ensure his respiratory tract open. If his breathing worsens, give him oxygen. If his breathing stops, give him artificial respiration immediately. Remember to seek medical advice.
