Diethylamine

Diethylamine is an organic compound that belongs to the amine family. It is a secondary amine with two ethyl groups attached to nitrogen, giving the formula C4H11N. It is a colorless, volatile liquid with a strong odor resembling ammonia and is miscible with water and many organic solvents.

Chemically, diethylamine is moderately basic and acts as a nucleophile at nitrogen. It forms salts with acids (for example, diethylammonium salts) and participates in reactions typical of secondary amines, such as alkylation and acylation. It can be used to introduce the diethylamino group into organic molecules.

Production and availability: diethylamine is produced industrially by amination of ethyl substrates, often via reaction of ethyl halides with ammonia or other amines, followed by purification to remove higher amines. It is sold as a chemical reagent and building block for laboratory and industrial synthesis.

Applications: it is widely used as a solvent in organic synthesis and as an intermediate in the manufacture of surfactants, dyes, pharmaceuticals, and pesticides. It serves as a precursor to other amines and to derivatives such as diethylaminoethyl chloride, used for modifying polymers and cellulose.

Safety and handling: diethylamine is flammable and can irritate the skin, eyes, and respiratory tract. Vapors may be harmful if inhaled. It should be used in a well-ventilated area, with appropriate personal protective equipment, and stored in tightly closed containers away from oxidizers.
