(TRIETHYL)AMINE

(Triethyl)amine is the chemical compound with the formula N(CH2CH3)3, commonly abbreviated Et3N. 
(Triethyl)amine is a commonly encountered in organic synthesis probably because it is the simplest symmetrically trisubstituted amine, i.e. a tertiary amine, that is liquid at room temperature. 
(Triethyl)amine possesses a strong fishy odor reminiscent of ammonia.

(Triethyl)amine is a widely used relative of triethylamine. 
(Triethyl)amineis also the smell of the hawthorn plant, and semen, among others 

(Triethyl)amine is commonly employed in organic synthesis as a base, most often in the preparation of esters and amides from acyl chlorides.
Such reactions lead to the production of hydrogen chloride which combines with (Triethyl)amine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. 
This reaction removes the hydrogen chloride from the reaction mixture, which is required for these reactions to proceed to completion (R, R' = alkyl, aryl):

R2NH + R'C(O)Cl + Et3N → R'C(O)NR2 + Et3NH+Cl-
Like other tertiary amines, (Triethyl)amine catalyzes the formation of urethane foams and epoxy resins. 
(Triethyl)amine is also useful in dehydrohalogenation reactions and Swern oxidations.

(Triethyl)amine is readily alkylated to give the corresponding quaternary ammonium salt:

RI + Et3N → Et3NR+I-

(Triethyl)amine, also known as (C2H5)3N or NET3, belongs to the class of organic compounds known as trialkylamines. 
These are organic compounds containing a trialkylamine group, characterized by exactly three alkyl groups bonded to the amino nitrogen. 
(Triethyl)amine is an ammoniacal and fishy tasting compound. 
(Triethyl)amine is found, on average, in the highest concentration within grape wine. 
This could make (Triethyl)amine a potential biomarker for the consumption of these foods. 
Based on a literature review a significant number of articles have been published on (Triethyl)amine.

(Triethyl)amine is commonly used as a base during the preparation of esters and amides from acyl chlorides. 
(Triethyl)amine is mainly used in the production of quaternary ammonium compounds for textile auxiliaries and quaternary ammonium salts of dyes. 
(Triethyl)amine acts as a catalyst and acid neutralizer for condensation reactions and is useful as an intermediate for manufacturing medicines, pesticides and other chemicals.

(Triethyl)amine is used as a neutralization agent for anionic stabilized waterborne resins (polyesters, alkyds, acrylic resins and polyurethanes containing carboxyl or other acidic groups). 
(Triethyl)amine is also utilized as a catalyst in the curing of epoxy and polyurethane systems.

(Triethyl)amine is a colorless to yellowish liquid with a strong ammonia to fish-like odor. 
(Triethyl)amine is a base commonly used in organic chemistry to prepare esters and amides from acyl chlorides. 
Like other tertiary amines,(Triethyl)amine catalyzes the formation of urethane foams and epoxy resins.
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).
