化学的特性

Colorless to yellowish liquid; fishy aroma.

化学的特性

Triethylamine is a colorless liquid. Strong ammonia odor.

物理的性質

Clear, colorless to light yellow flammable liquid with a strong, penetrating, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were <400 μg/m3 (<100 ppbv) and 1.1 mg/m3 (270 ppbv), respectively (Hellman and Small, 1974). An odor threshold concentration of 0.032 ppbv was determined by a triangular odor bag method (Nagata and Takeuchi, 1990).

使用

Catalytic solvent in chemical synthesis; accelerator activators for rubber; wetting, penetrating, and waterproofing agents of quaternary ammonium types; curing and hardening of polymers (e.g., corebinding resins); corrosion inhibitor; propellant.

調製方法

Triethylamine is prepared by a vapor phase reaction of ammonia with ethanol or reaction of N,N-diethylacetamide with lithium aluminum hydride (Windholz et al 1983). It may also be produced from ethyl chloride and ammonia under heat and pressure (Hawley 1981) or by vapor phase alkylation of ammonia with ethanol (HSDB 1988). U.S. production is estimated at greater than 22,000 tons in 1972 (HSDB 1988).

定義

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

Aroma threshold values

High strength odor, fishy type; recommend smelling in a 0.01% solution or less.

一般的な説明

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.

反応プロフィール

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.

健康ハザード

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.

健康ハザード

Eye irritation and corneal edema have been reported from exposures in industry (Beard and Noe, 1981; Akesson et al 1985). Triethylamine may also be irritating to skin and mucous membranes (Windholz et al 1983).

火災危険

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.

工業用途

Triethylamine is used as an anti-livering agent for urea- and melamine-based enamels and in the recovery of gelled paint vehicles (HSDB 1988). It is also used as a catalyst for polyurethane foams, a flux for copper soldering, and as a catalytic solvent in chemical synthesis (Hawley 1981). Triethylamine is used in accelerating activators for rubber; as a corrosion inhibitor for polymers; a propellant; wetting, penetrating, and waterproofing agent of quaternary ammonium compounds; in curing and hardening of polymers (i.e. core-binding resins); and as a catalyst for epoxy resins (Hamilton and Hardy, 1974).

安全性プロファイル

Moderately 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.

職業ばく露

Triethylamine 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.

環境運命予測

Photolytic. Low et al. (1991) reported that the photooxidation of aqueous tertiary amine solutions by UV light in the presence of titanium dioxide resulted in the formation of ammonium and nitrate ions.
Chemical/Physical. Triethylamine reacted with NOx in the dark to form diethylnitrosamine. In an outdoor chamber, photooxidation by natural sunlight yielded the following products: diethylnitramine, diethylformamide, diethylacetamide, ethylacetamide, diethylhydroxylamine, ozone, acetaldehyde, and peroxyacetyl nitrate (Pitts et al., 1978).

代謝

There have been few studies on the metabolism of industrially important aliphatic amines such as triethylamine. It is generally assumed that amines not normally present in the body are metabolized by monoamine oxidase and diamine oxidase (histaminase).
Ultimately ammonia is formed and will be converted to urea. The hydrogen peroxide formed is acted upon by catalase and the aldehyde formed is thought to be converted to the corresponding carboxylic acid by the action of aldehyde oxidase (Beard and Noe 1981).

輸送方法

UN1296 Triethylamine, Hazard Class: 3; Labels: 3-Flammable liquid, 8-Corrosive material.

純化方法

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.]

不和合性

A 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.

廃棄物の処理

Controlled incineration (incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions).
