Triethylamineis a colourless volatile liquid with a strong fishy odor reminiscent of ammonia and is also the smell of the hawthorn plant. Like diisopropylethylamine (Hünig’s base), triethylamine is commonly encountered in organic synthesis. Triethylamine 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 triethylamine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. Triethylamine is mainly used in the production of quaternary ammonium compounds for textile auxiliaries and quaternary ammonium salts of dyes. It is also a catalyst and acid neutralizer for condensation reactions and is useful as an intermediate for manufacturing medicines, pesticides and other chemicals.
