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

Diethylamine is a colorless, strongly alkaline, highly inflammable, liquid. It 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 oxidizers, 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. It has several applications in industries, such as organic synthesis of resins, as rubber accelerator, pharmaceuticals, pesticides, dyes, electroplating operations, and as a polymerization inhibitor.

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.

Health Hazard

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

Health Hazard

Exposures to diethylamine cause adverse health effects. The symptoms of toxicity include irritation of skin, eyes, and mucous membrane. The acute oral LD50 and acute dermal LD50 in rats and rabbits are 540 and 580 mg/kg, respectively, and the acute inhalation LC50 (4 h) in rats is 4000 ppm. The pathomorphological changes caused by diethylamine include lungs, liver, and kidneys, cellular infi ltration, bronchopneumonia, parenchymatous degeneration, and nephritis.

Safety Profile

Moderately toxic by ingestion, inhalation, and skin contact. A skin and severe eye irritant. Exposure to strong vapor can cause severe cough and chest pains. Contact with liquid can damage eyes, possibly permanently; contact with skin causes necrosis and vesciculation. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. Explodes on contact with dicyanofurazan. Violent reaction with sulfuric acid. Ignites on contact with cellulose nitrate of sufficiently high surface area. When heated to decomposition it emits toxic fumes of NOx. See also MINES.

storage

Diethylamine should be protected from physical damage. It should be kept stored in a cool, dry, well-ventilated location, away from incompatible chemical substances and away from fi re hazard and smoking areas. The containers should be bonded and grounded for transfer to avoid static sparks. Storage and use areas should be no smoking areas.

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.

Precautions

Occupational workers and users should be very careful during the use and chemical management of diethylamine. Workers should wear impervious protective clothing, including boots, gloves, a laboratory coat, apron or coveralls, as appropriate, to prevent skin contact. The chemical is very hazardous, corrosive, and harmful, and is a very flammable liquid and vapor. Exposures to vapor may cause fl ash fi re. It causes burns and adverse effects to the cardiovascular system. Workers should use chemical safety goggles and a full-face shield to avoid splashing of the chemical substance. An eye-wash fountain and quickdrench facilities in the work area should be maintained by the chemical management unit.
