개요

에틸렌다이아민(Ethylenediamine)은 유기화합물의 일종이다. 킬레이트제로 작용할 수 있으며 리간드일 경우 en으로 축약시켜 표기하기도 한다. 강염기성이며, 암모니아 냄새가 난다.

용도

에틸렌다이아민은 두 자리 리간드로 작용할 수 있어서, 금속 이온과 배위하여 착물을 형성한다. 따라서 특정한 금속 이온을 농축, 분리, 제거, 이동하는 데 사용될 수 있다.

독성

에틸렌다이아민은 체내에 흡수되었을 때 알레르기 반응을 일으킬 수 있다. 피부에 염증을 일으킬 수 있으며 점액질 막을 파괴시킬 수 있다.

개요

Ethylenediamine is used in numerous industrial proces ses 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 cross react with triethylenetetramine and diethylenetriamine. Ethylenediamine was 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 tab lets.

화학적 성질

Ethylenediamine, a polyamine, is a strongly alkaline, colorless, clear, thick liquid. Ammonia odor. A solid below 8.5℃. The Odor Threshold is 1.0 ppm

물리적 성질

Clear, colorless, volatile, slight viscous, hygroscopic liquid with a sweet, ammonia-like odor. The average least detectable odor threshold concentrations in water at 60 °C and in air at 40 °C were 12 and 52 mg/L, respectively (Alexander et al., 1982).

용도

[Note—Edamine is the recommended contraction for the ethylenediamine radical.].

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.

일반 설명

Ethylenediamine is a linear aliphatic diamine, widely used as a building block in organic synthesis. It readily forms heterocyclic imidazolidine derivatives, because of its bifunctional nature, having two amines. Ethylenediamine is also utilized as a raw material for the synthesis of chelating agents, polymers, agrochemicals and pharmaceutical intermediates.

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

Ethylenediamine is a severe skin irritant, producing 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, is much 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

Reactivity with Water Gives off heat, but reaction is not hazardous; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

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).
