정의

ChEBI: An alkane-alpha,omega-diamine in which the alkane is ethane.

생산 방법

The production of ethylene-1,2-diamine (EDA) is by the catalytic amination of monoethanolamine or the reaction of aqueous ammonia with 1,2-dichloroethane (Spitz 1979). U.S. Production is estimated at greater than 33,000 tons in 1975.

정의

An organic compound, H2NCH2CH2NH2. It is important in inorganic chemistry because it may function as a bidentantate ligand, coordinating to a metal ion by the lone pairs on the two nitrogen atoms. In the names of complexes it is given the abbreviation en.

공기와 물의 반응

Highly flammable. Hygroscopic. Fumes in the air. Water soluble. Biodegrades readily.

반응 프로필

A base. Highly reactive with many compounds. Can react violently with acetic acid, acetic anhydride, acrolein, acrylic acid, acrylonitrile, allyl chloride, carbon disulfide, chlorosulfonic acid, epichlorohydrin, ethylene chlorohydrin, hydrogen chloride, mesityl oxide, nitric acid, oleum, AgClO4, sulfuric acid, beta-propiolactone and vinyl acetate. Incompatible with strong acids, strong oxidizers (perchlorate salts), and chlorinated organic compounds. Ethylenediamine is also incompatible with halogenated organic compounds and metal halides. May react with nitromethane and diisopropyl peroxydicarbonate. May ignite on contact with cellulose nitrate. Readily absorbs carbon dioxide from the air to give crusty solid deposits. . Ethylenediamine reacts violently with ethylene chlorohydrin. (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 1554.).

위험도

Toxic by inhalation and skin absorption, strong irritant to skin and eyes. Flammable, moderate fire risk. Questionable carcinogen.

건강위험

Vapor inhalations at a concentration of 200 ppm for 5 to 10 minutes will lead to nasal irritation and produce a tingling sensation. Inhalation at concentrations of 400 ppm or greater leads to severe nasal irritation. Respiratory irritation may result. Many individuals are hypersensitive to Ethylenediamine exposure; therefore, safe threshold limits are difficult to set.

건강위험

Human subjects found 100 p.p.m. EDA for a few seconds to be inoffensive but higher concentrations of 200 and 400 p.p.m. produced noticeable irritation of the nasal mucosa (HSDB 1988). Acute EDA ingestion will cause burns of the mouth, esophagus and possibly stomach. Eye contact would be expected to produce a serious burn due to the corrosiveness of the compound. Acute exposure to the skin is likely to produce a skin burn, while chronic exposure will cause a serious burn.
EDA, in addition, is a potent allergen causing hypersensitization in exposed individuals (HSDB 1988). Because of such reactions, it has been difficult to establish threshold limits that will prevent the hypersensitization response. Allergic reactions to EDA in hair and nail care products have been observed among beauty operators, patrons and their husbands (Arena 1979). In the lacquer and shellac industries, exposure to EDA used as a solvent or paint thinner has produced wheezing, heaviness in the chest, severe asthma, allergic coryza and skin rashes (Arena 1979). Workmen exposed to EDA occasionally see halos around objects and have some blurring of vision, presumably due to the effects on the corneal epithelium (Grant 1974). In a study population of 1158 paid volunteers given a patch test, 0.43% showed a positive reaction to EDA (Prystowsky et al 1979).

건강위험

Ethylenediamine is a severe skin irritant, pro ducing sensitization, an allergic reaction andblistering on the skin. Pure liquid on contact with the eyes can damage vision. A25% aqueous solution can be injurious to theeyes. Inhalation of its vapors can producea strong irritation to the nose and respiratory tract leading to chemical pneumonitis and pulmonary edema. Such irritation inhumans with symptoms of cough and dis tressed breathing may be noted at concentrations of >400 ppm. Repeated exposure tohigh concentrations of this substance in airmay cause lung, liver, and kidney damage.The toxicity of this compound, however, ismuch less than that of ethylenimine.The acute oral toxicity value in animalswas low to moderate. An oral LD50 value inrats is 500 mg/kg (NIOSH 1986).

화재위험

Burning rate: 2.2 mm/minute. When exposed to heat or flame, the material has a moderate fire potential. The material can react readily with oxidizing materials. Containers may explode in heat of fire. Material emits nitrogen oxides when burned. Avoid carbon disulfide, silver perchlorate, imines, oxidizing materials. Stable. Hazardous polymerization may not occur.

화학 반응

공업 용도

EDA functions as a reactive intermediate in the synthesis of carbamate fungicides and in the preparation of dyes, synthetic waxes, resins, insecticides and asphalt wetting agents (Parmeggiani 1983). EDA is a solvent for casein, albumin, shellac, and sulfur; an emulsifier; a stabilizer for rubber latex; an inhibitor in antifreeze solutions; and a pharmaceutic aid (aminophylline injection stabilizer) (Windholz 1983). It is also an important ingredient in hair-settings, cold wave lotions, and nail polish (Arena 1979).

색상 색인 번호

Ethylenediamine is used in numerous industrial processes as a solvent for casein or albumin, as a stabilizer in rubber latex, and as a textile lubricant. It can be found in epoxy resin hardeners, cooling oils, fungicides, and waxes. Contact dermatitis from ethylenediamine is almost exclusively due to topical medicaments. Occupational contact dermatitis in epoxy resin systems is rather infrequent. Ethylenediamine can crossreact with triethylenetetramine and diethylenetriamine. Ethylenediamine was found to be responsible for sensitization in pharmacists handling aminophylline suppositories, in nurses preparing and administering injectable theophylline, and in a laboratory technician in the manufacture of aminophylline tablets

Safety Profile

환경귀착

Chemical/Physical. Absorbs carbon dioxide forming carbonates (Patnaik, 1992; Windholz et al., 1983).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 893 mg/L. The adsorbability of the carbon used was 21 mg/g carbon (Guisti et al., 1974).

신진 대사

EDA is absorbed through the skin (Beard and Noe 1981). The penetration rates, distribution and excretion of topically applied [14C]-ethylenediamine have been studied in the rat (Yang et al 1987). Male Wistar rats were percutaneously exposed to solutions of 10, 25 or 50% EDA over about 10% of the body surface. Absorption of EDA was concentration dependent, with about 12, 55 and 61% being absorbed at the 70, 25 and 50% concentration respectively. The terminal plasma half-life of EDA was approximately 4.5 h and the major route of excretion was via the urine. The authors concluded that skin absorption is relatively low and the reduced absorption at higher EDA concentrations may be due to epidermal damage.
When male rats were given 5, 50 or 500 mg/kg doses of [14C]-EDA by oral, endotracheal and i.v. routes, urinary excretion accounted for 42-65% of the administered radioactivity (Yang and Tallant 1982). Fecal excretion amounted to 5-32% of the dose, depending on the route and 6-9% was eliminated in expired air as 14CO2. As the dosage increased from 5 to 50 to 500 mg/kg, there was a pattern of accumulated tissue EDA with a corresponding decrease in metabolite formation. The route of administration did not appear to change the metabolic profile. The major urinary metabolite in the rat was N-acetylethylenediamine (Yang and Tallant 1982). Cotgreave and Caldwell (1983) found that EDA was not detectable in the plasma 2 h after oral and i.v. administration of aminophylline in three healthy human subjects. Davies et al (1983) observed that ethylenediamine uptake in rat brain slices was temperature-dependent and appeared to take place by both sodium dependent and sodium independent mechanisms. Yang et al (1984a) demonstrated age- and, to a lesser extent, sex-related differences in the pharmacokinetics of EDA in Fischer 344 rats.

Purification Methods

It forms a constant-boiling (b 118.5o, monohydrate, m 10o) mixture with water (23w/w%). [It is hygroscopic and miscible with water.] Recommended purification procedure [Asthana & Mukherjee in J.F.Coetzee (ed), Purification of Solvents, Pergamon Press, Oxford, 1982 cf p 53]: to 1L of ethylenediamine is added 70g of type 5A Linde molecular sieves and shaken for 12hours. The liquid is decanted and shaken for a further 12hours with a mixture of CaO (50g) and KOH (15g). The supernatant is fractionally distilled (at 20:1 reflux ratio) in contact with freshly activated molecular sieves. The fraction distilling at 117.2o /760mm is collected. Finally it is fractionally distilled from sodium metal. All distillations and storage of ethylenediamine should be carried out under nitrogen to prevent reaction with CO2 and water. The material containing 30% water is dried with solid NaOH (600g/L) and heated on a water bath for 10hours. Above 60o, separation into two phases takes place. The hot ethylenediamine layer is decanted off, refluxed with 40g of sodium for 2hours and distilled [Putnam & Kobe Trans Electrochem Soc 74 609 1938]. Ethylenediamine is usually distilled under nitrogen. Alternatively, it is dried over type 5A Linde molecular sieves (70g/L), then a mixture of 50g of CaO and 15g of KOH/L, with further dehydration of the supernatant with molecular sieves followed by distillation from molecular sieves and, finally, from sodium metal. A spectroscopically improved material is obtained by shaking with freshly baked alumina (20g/L) before distillation. [Beilstein 4 IV 1166.]
