Diethylamine Chemical Properties,Uses,Production

Description

Diethylamine is a colourless, strongly alkaline, fish odour liquid, and highly inflammable. It has an ammonia-like odour and is completely soluble in water. On burning, diethylamine releases ammonia, carbon monoxide, carbon dioxide, and nitrogen oxides. It is incompatible with several chemical substances such as strong oxidisers, acids, cellulose nitrate, some metals, and dicyanofuroxan. N-nitrosamines, many of which are known to be potent carcinogens, may be formed when diethylamine comes in contact with nitrous acid, nitrates, or atmospheres with high nitrous oxide concentrations. The applications of Diethylamine are numerous. Diethylamine is used in the production of pesticides. It is used in a mixture for the production of DEET which goes into the repellents that are found readily in supermarkets for general use. Diethylamine is also mixed with other chemicals to form Diethylaminoethanole, which is used mainly as a corrosion inhibitor in water treatment facilities as well as production of dyes, rubber, resins, and pharmaceuticals. Diethylamine is also used in manufacture of basic chemicals and pharmaceuticals.

Chemical Properties

Colorless liquid

Definition

ChEBI: A secondary aliphatic amine where both N-substituents are ethyl.

General Description

A clear colorless liquid with an ammonia-like odor. Density 5.9 lb / gal. Flash point -15°F. A respiratory irritant. Corrosive to the eyes and skin. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion.

Air & Water Reactions

Highly flammable. Soluble in water. Sensitive to heat. May be sensitive to prolonged exposure to air.

Reactivity Profile

Diethylamine is a colourless, strongly alkaline, fish odour liquid, and highly inflammable. It has an ammonia-like odour and is completely soluble in water.Causes ignition on contact with cellulose nitrate. Explodes on contact with dicyanofurazan or dicyanofuroxan. Attacks some forms of plastics, rubber and coatings.
On burning, diethylamine releases ammonia, carbon monoxide, carbon dioxide, and nitrogen oxides. It is incompatible with several chemical substances such as strong oxidisers, acids, cellulose nitrate, some metals, and dicyanofuroxan. N-nitrosamines, many of which are known to be potent carcinogens, may be formed when diethylamine comes in contact with nitrous acid, nitrates, or atmospheres with high nitrous oxide concentrations.

Health Hazard

Irritation and burning of eyes, skin, and respiratory system. High concentration of vapor can cause asphyxiation.

Purification Methods

Dry diethylamine with LiAlH4 or KOH pellets. Reflux with, and distil it from, BaO or KOH. Convert it to the p-toluenesulfonamide and crystallise to constant melting point from dry pet ether (b 90-120o), then hydrolyse with HCl, excess NaOH is added, and the amine is passed through a column of activated alumina. Redistil the amine and dry it with activated alumina before use [Swift J Am Chem Soc 64 115 1942]. [Beilstein 4 III 313.] § A polystyrene diethylaminomethyl supported version is commercially available.
