Diethylamine Usage And Synthesis 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. Physical properties Colorless liquid with a fishy, ammonia-like odor. Its chemistry is governed by the unshared electron pair on the nitrogen, thus it tends to react with acids to form salts.
Occurrence Diethylamine occurs in low concentrations in food and other biological materials. Concentrations in p. Pickled vegetables contain Interest in the occurrence of diethylamine in foods arises in part because of its possible formation of a carcinogenic N-nitroso derivative Neurath et al Diethylamine has been reported in the exhaust from a gasoline engine Hampton et al Uses In flotation agents, resins, dyes, resins, pesticides, rubber chemicals, and pharmaceuticals; selective solvent; polymerization and corrosion inhibitors; petroleum chemicals; electroplating; organic synthesis.
Uses Diethylamine is manufactured by heating ethyl chloride and alcoholic ammonia under pressure or by hydrogenation of aziridines in the presence of catalysts. DEA is used as a solvent, as a rubber accelerator, in the organic synthesis of resins, dyes, pesticides, and pharmaceuticals, in electroplating, and as a polymerization inhibitor. Other applications include uses as a corrosion inhibitor. It was reported noneffective as a skin depigmentator. Production Methods Diethylamine is produced using the three methods also used for the manufacture of ethylamine with very slight modification.
The most widely used method is the passing of ammonia and ethanol over a catalyst such as alumina or silica Schweizer et al Diethylamine can be separated from the mixture by selective distillations and extractions.
This secondary amine can also be produced by the other two methods which involve: 1 passing ammonia, ethanol, and hydrogen over a dehydrogenation catalyst; and 2 passing ammonia and an aldehyde or ketone and hydrogen over a hydrogenation catalyst. General Description A clear colorless liquid with an ammonia-like odor. Density 5.
A respiratory irritant. Corrosive to the eyes and skin. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion.
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.
Causes ignition on contact with cellulose nitrate. Explodes on contact with dicyanofurazan or dicyanofuroxan. Attacks some forms of plastics, rubber and coatings. Health Hazard Diethylamine can be harmful if it is inhaled, swallowed, or in contact with skin. Vapors can irritate the eyes and cause irritation of the respiratory tract, leading to coughing and chest pain.
Liquid diethylamine can cause severe burns to the eyes and skin. Vision became misty and halos appeared several hours after workmen were exposed to the vapors of amines such as diethylamine Grant The edema of the corneal epithelium, which is principally responsible for the disturbances in vision, clears after one or more days, depending on the severity of exposure.
Photophobia and discomfort from roughness of the corneal surface also can occur after greater exposure to the amine. Industrial uses Diethylamine, like many of the other short chain aliphatic amines, has achieved widespread industrial use as an intermediate in the manufacture of a number of commercial products.
Among these are included insecticides, pharmaceuticals, textile finishing agents, and corrosion inhibitors Hawley ; Schweizer et al 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. Environmental fate Photolytic. Low et al. Diethylamine reacted with NOx in the dark forming diethylnitrosamine. In an outdoor chamber, photooxidation by natural sunlight yielded the following products: diethylnitramine, diethylformamide, diethylacetamide, ethylacetamide, ozone, acetaldehyde, and peroxyacetyl nitrate Pitts et al.
Reacts with mineral acids forming water-soluble salts Morrison and Boyd, Metabolism Little information is available regarding the metabolism of diethylamine. The amine can be readily absorbed from the respiratory and gastrointestinal tract. It has been reported that following oral administration of diethylamine hydrochloride to humans, much of the amine was recovered in the urine Beard and Noe This suggests that it is not readily metabolized and, therefore, may not be a substrate for monoamine oxidase.
When administered intraperitoneally to rats, it was moderately inhibitory with respect to liver monoamine oxidase Valiev Diethylamine may serve as a precursor for the formation of the reportedly carcinogenic N-nitrosoamines and, indeed, when a diethylamine containing liquid was examined for nitrosation reactions under simulated conditions of the human stomach, N-nitrosodiethylamine was formed Ziebarth 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. Convert it to the p-toluenesulfonamide and crystallise to constant melting point from dry pet ether b o , then hydrolyse with HCl, excess NaOH is added, and the amine is passed through a column of activated alumina.
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. Shandong chuangyingchemical Co. Capot Chemical Co. Henan Tianfu Chemical Co.
