121-44-8 Usage

Stimulus data

Eyes-rabbit 250 mg severe

Health Hazard

Vapors irritate nose, throat, and lungs, causing coughing, choking, and difficult breathing. Contact with eyes causes severe burns. Clothing wet with chemical causes skin burns.

Reactivity Profile

Triethylamine reacts violently with oxidizing agents. Reacts with Al and Zn. Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.


Flammable liquids

Purification Methods

Dry triethylamine with CaSO4, LiAlH4, Linde type 4A molecular sieves, CaH2, KOH, or K2CO3, then distil it, either alone or from BaO, sodium, P2O5 or CaH2. It has also been distilled from zinc dust, under nitrogen. To remove traces of primary and secondary amines, triethylamine has been refluxed with acetic anhydride, benzoic anhydride, phthalic anhydride, then distilled, refluxed with CaH2 (ammonia-free) or KOH (or dried with activated alumina), and again distilled. Another purification method involved refluxing for 2hours with p-toluenesulfonyl chloride, then distilling. Grovenstein and Williams [J Am Chem Soc 83 412 1961] treated triethylamine (500mL) with benzoyl chloride (30mL), filtered off the precipitate, and refluxed the liquid for 1hour with a further 30mL of benzoyl chloride. After cooling, the liquid was filtered, distilled, and allowed to stand for several hours with KOH pellets. It was then refluxed with, and distilled from, stirred molten potassium. Triethylamine has been converted to its hydrochloride (see brlow), crystallised from EtOH (to m 254o), then liberated with aqueous NaOH, dried with solid KOH and distilled from sodium under N2. [Beilstein 4 H 99, 4 I 348, 4 II 593, 4 III 194, 4 IV 322.]

Extinguishing agent

Dry, dry sand, carbon dioxide, foam


It is produced by ethanol and ammonia in the presence of hydrogen, in containing Cu-Ni-clay catalyst reactor under heating conditions (190 ± 2 ℃ and 165 ± 2 ℃) reaction. The reaction also produces ethylamine and diethylamine, products were condensed and then absorption by ethanol spray to obtain crude triethylamine, through the final separation, dehydration and fractionation, pure triethylamine is obtained.

Flammability hazard characteristics

In case of fire, high temperature, oxidant, it is flammable, combustion produces toxic fumes of nitrogen oxides


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.

Toxicity grading



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.

Fire Hazard

Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Storage Characteristics

Treasury ventilation low-temperature drying, stored separately from oxidants, acids

Health Effects

Triethylamine can affect you when inhaled and by passing through the skin.
  1. Contact can severely irritate and bum the skin and eyes with possible eye damage.
  2. Exposure can irritate the eyes, nose and throat.
  3. Inhaling Triethylamine can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical mergency.
  4. Triethylamine may cause a skin allergy.
  5. Triethylamine may affect the liver and kidneys.
  6. Triethylamine is a flammable liquid and a dangerous fire hazard.


ChEBI: A tertiary amine that is ammonia in which each hydrogen atom is substituted by an ethyl group.


  • It can be used to reduce the alkali in the reaction.

  • Alkylation reaction
  • Oxidation reaction

General Description

A clear colorless liquid with a strong ammonia to fish-like odor. Flash point 20°F. Vapors irritate the eyes and mucous membranes. Less dense (6.1 lb / gal) than water. Vapors heavier than air. Produces toxic oxides of nitrogen when burned.

Explosive hazardous characteristics

Mixed with air can be explosive
