화학적 성질
Ethylamine is a colorless gas or water-white liquid (below 17℃). Strong, ammonia-like odor. Shipped as a liquefied compressed gas.물리적 성질
Colorless liquid or gas with a strong ammonia-like odor. An experimentally determined odor threshold concentration of 21 ppbv was reported by Leonardos et al. (1969). Experimentally determined detection and recognition odor threshold concentrations were 500 μg/m3 (270 ppbv) and 1.5 mg/m3 (810 ppbv), respectively (Hellman and Small, 1974).용도
Ethylamine is used in the manufacture ofdyes and resins, as a stabilizer for rubberlatex, and in organic synthesis.정의
ethylamine: A colourless flammablevolatile liquid, C2H5NH2; r.d. 0.69;m.p. –81°C; b.p. 16.6°C. It is a primaryamine made by reactingchloroethane with ammonia andused in making dyes.일반 설명
A colorless liquid or a gas (boiling point 62°F) with an odor of ammonia. Flash point less than 0°F. Density of liquid 5.7 lb / gal. Corrosive to the skin and eyes. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Exposure of the closed container to intense heat may cause Ethylamine to rupture violently and rocket.공기와 물의 반응

Incompatible with cellulose nitrate. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Also incompatible with oxidizing agents. A chemical base. Neutralizes acids to form salts plus water in an exothermic reaction Dissolves most paints, plastics and rubber .위험도
Strong irritant. Flammable, dangerous fire risk, flammable limits in air 3.5–14%.건강위험
Ethylamine is a severe irritant to the eyes,skin, and respiratory system. The pure liquidor its highly concentrated solution can causecorneal damage upon contact with eyes. Skincontact can result in necrotic skin burns.Rabbits exposed to 100 ppm ethylaminefor 7 h/day, 5 days/week for 6 weeks mani fested irritation of cornea and lung, and liverand kidney damage (ACGIH 1986). A 4-hourexposure to 3000 ppm was lethal to rats. Theacute oral and dermal toxicity of this com pound was moderate in test animals.
LD50 value, oral (rats): 400 mg/kg
LD50 value, skin (rabbits): 390 mg/kg.

Ethylamine has achieved widespread use as an intermediate in the manufacture of a variety of products. It is used as a solvent for dyes, resins, and oils and as a vulcanization accelerator for sulfur-cured rubbers as well as a stabilizer for rubber latex (NIOSH 1981; HSDB 1989). The amine is used in the production of alkyl isocyanates for intermediates in the manufacture of products such as pharmaceuticals and resins. It also serves as an intermediate in the manufacture of triazine herbicides, a corrosion inhibitor (1,3-diethyl thiourea), and an agent used in wash and wear fabrics (dimethylolethyltriazone). Copious salts of ethylamine can also be used in the refining of petroleum and vegetable oil (Sittig 1981). The amine also has uses as an industrial solvent and as a chemical initiator in the preparation of various solvents (HSDB 1989).Safety Profile
A poison by ingestion, skin contact, and intravenous routes. Moderately toxic by inhalation. A severe eye irritant. A very dangerous fire hazard when exposed to heat or flame. Moderate explosion hazard when exposed to spark or flame. Keep away from heat and open flame, can react vigorously with oxidizing materials. To fight fire, stop flow of gas, use alcohol foam, dry chemical. Incompatible with cellulose nitrate or oxidzers. When heated to decomposition it emits toxic fumes of NOx. See also MINES.잠재적 노출
Monoethylamine (MEA) is used as an intermediate in the manufacture of the following chemicals: triazine herbicides, 1,3-diethylthiourea (a corrosion inhibitor); ethylamino-ethanol; 4-ethylmorpholine (urethane foam catalyst); ethyl isocyanate; and dimethylolethyltriazone (agent used in wash-and-wear fabrics). The cuprous chloride salts of MEA are used in the refining of petroleum and vegetable oil.환경귀착
Photolytic. The rate constant for the reaction of ethylamine and ozone in the atmosphere is 2.76 x 10-20 cm3/molecule?sec at 296 K (Atkinson and Carter, 1984). Atkinson (1985) reported a rate constant of 6.54 x 10-11 cm3/molecule?sec for the vapor-phase reaction of ethylamine and OH radicals at 25.5 °C. The half-life for this reaction is 8.6 h.Low et al. (1991) reported that the photooxidation of aqueous primary amine solutions by UV light in the presence of titanium dioxide resulted in the formation of ammonium and nitrate ions.
Chemical/Physical. Reacts with OH radicals possibly forming acetaldehyde or acetamide (Atkinson et al., 1978). When ethylamine over kaolin is heated to 600 °C, hydrogen and acetonitrile formed as the major products. Trace amounts of ethylene, ammonia, hydrogen cyanide, and methane were also produced. At 900 °C, however, acetonitrile was not produced (Hurd and Carnahan, 1930).
Reacts with mineral acids forming water-soluble salts (Morrison and Boyd, 1971).
신진 대사
Ethylamine is readily absorbed from the respiratory and gastrointestinal tracts. When administered to humans as the HC1 form, about 32% of the ethylamine could be recovered in the urine (Rechenberger 1984). It appears that ethylamine is slowly oxidized by monoamine oxidase to form hydrogen peroxide and the corresponding aldehyde. Subsequently, the peroxide is removed by catalase and the aldehyde is likely converted to its carboxylic acid by aldehyde oxidase (Beard andNoe 1981).As with other alkylamines, a potential exists for in vivo nitrosation of ethylamine from foods by the preservative sodium nitrite under the acidic conditions found in the stomach (Lin et al 1983,1984).
저장
Ethylamine should be stored in a flammable-liquids storage room or cabinet. It shouldbe stored away from oxidizing materials andsources of ignition. It is shipped in steelcylinders or drums.운송 방법
UN1036, Ethylamine, Hazard Class: 2.1; Labels: 2.1-Flammable gas. Ethylamine, aqueous solution with not ,50% but not .70% ethylamine, Hazard Class: 3; Labels: 3-Flammable liquid, 8-Corrosive material. Cylinders must be transported in a secure upright position, in a wellventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.Purification Methods
Condense it in an all-glass apparatus cooled by circulating ice-water, and store it with KOH pellets below 0o. [Beilstein 4 IV 307.]비 호환성
