Triethylamine Usage And Synthesis
OutlineTriethylamine (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.
UsesTriethylamine 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.

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

  • Alkylation reaction
  • Oxidation reaction
Health EffectsTriethylamine 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.

General DescriptionA 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.
Reactivity ProfileTriethylamine 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.
Health HazardVapors irritate nose, throat, and lungs, causing coughing, choking, and difficult breathing. Contact with eyes causes severe burns. Clothing wet with chemical causes skin burns.
Fire HazardFlammable/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.
Safety ProfileModerately toxic by ingestion and skin contact. Mildly toxic by inhalation. Human systemic effects: visual field changes. Experimental reproductive effects. Mutation data reported. A skin and severe eye irritant. Can cause kidney and liver damage. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. Complex with dinitrogen tetraoxide explodes below 0°C when undduted with solvent. Exothermic reaction with maleic anhydride above 150°C. Can react with oxidzing materials. Incompatible with N2O4. To fight fire, use CO2, dry chemical, alcohol foam. When heated to decomposition it emits toxic fumes of NOx.
Potential ExposureTriethylamine is and aliphatic amine used as a solvent; corrosion inhibitor; in chemical synthesis; and accelerator activators; paint remover; base in methylene chloride or other chlorinated solvents. TEA is used to solubilize 2,4,5-T in water and serves as a selective extractant in the purification of antibiotics. It is used to manufacture quaternary ammonia compounds and octadecyloxymethyltriethylammonium chloride; an agent used in textile treatment.
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water, or milk. Do not induce vomiting. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Purification MethodsDry 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.]
IncompatibilitiesA strong base. Violent reaction with strong acids; halogenated compounds; and strong oxidizers. Attacks some forms of plastics, rubber and coatings. Corrosive to aluminum, zinc, copper, and their alloys in the presence of moisture. Reaction with nitrosating agents (e.g., nitrites, nitrous gases, and nitrous acid) capable of releasing carcinogenic nitrosamines.
Waste DisposalControlled incineration (incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions).
