Ethylamine Chemical Properties,Uses,Production

Product characteristics

Ethylamine, also known as aminoethane or ethylamine, is colorless transparent liquid and highly volatile. It has ammonia flavor and is flammable. Its relative molecular mass is 45.09; relative density 0.6829; melting point-80.6 ℃; boiling point 16.6℃; flash point-17℃(closed). It will spontaneously combust in air at 555℃. Its refractive index is 1.3663. It is miscible with water, ethanol and ether. It has strong alkaline and can react with mineral acid to form water-soluble salt. It can also react with acyl group to form acyl amide and react with nitrous acid to generate nitrosamines. It can be oxidized to form hydroxylamine or oxime. When burning in the air, the flame is light blue. It can react with phosgene to form carbonyl chloride and react with acrylonitrile to generate aminopropionitrile. It can strongly stimulate the skin and mucous membranes. Rat-oral LD50 is 400mg/kg. Storage should use stainless steel containers and stainless steel valves.
Ethylamine can be prepared by the reaction of ethyl iodide (ethyl chloride) with ammonia in liquid ammonia (ethanol solution) or by the high-pressure hydrogenation of acetonitrile in the catalyst of nickel. Ethylamine is mainly used as the raw materials of triazine herbicides to produce Atrazine (selective herbicides) and Simazine (pre-emergence herbicides of dry field). It can also be used as the raw materials of dyes, surfactants, detergents, lubricants and ion exchange resins, the stabilizer of resin and rubber slurry, antioxidants, the additives of oil refining, metallurgical mineral processing agents, pharmaceutical raw materials, solvents and extractants. The oxalates of the ethylamine can be used medicinally.

Chemical properties

colorless volatile liquid; ammonia smell; alkaline; miscible with water, ethanol and ether.


1. Used for the production of dyes, pharmaceuticals, surfactants, herbicides, rubber vulcanization accelerator and ion exchange resins.
2. Ethylamine is the intermediates of antiseptics of cymoxanil and ethirimol, pesticide of amphetamines, and herbicides of atrazine, west grass net, simazine, benthiocarb and napropamide.
3. Ethylamine can be used for the production of triazine herbicides, including atrazine and simazine. Both herbicides use cyanuric chloride as raw materials, and also have similar production processes. (also known as Terrazine) has wider range of applications than Simazine, but also can kill the anti-Simazin weeds. Atrazine is developed and produced by the Swiss Geigy company in 1985, and later developed into the world's largest production herbicide. Ethylamine is also used in the production of dyes, rubber accelerators, surfactants, antioxidants, ion exchange resins, aircraft fuels, solvents, detergents, lubricants, metallurgical mineral processing agent, as well as the production of cosmetics and pharmaceuticals.
4. Used for organic synthesis, and also used as dye intermediates, stabilizers and emulsifiers
5. Used for the synthesis of organic resins and dyes.

Production methods

1. ethanol (gas phase) amination method: feed ethanol and ammonia by the ratio of 4: 1, and make them react with the dehydration catalysis of alumina at the temperature of 350-400℃ and under the pressure of 2.45-2.94MPa. In addition to the formation of ethylamine, the side reaction also produce diethylamine, triethylamine, ether, acetonitrile and ethylene. The crude ethylamine obtained by the condensation of the reaction gas is then taken for distillation to gather ammonia, with the content of more than 95%. Generally 50% aqueous solution is used as the commodity, per ton of which consumes ethano (95%) of about 1400kg.
2. Acetaldehyde hydrogen aminiation method: the reaction of acetaldehyde, hydrogen and ammonia with the catalysis of nickel can produce ethylamine. Firstly, the structure catalyst with nickel as the main catalyst, reduced copper and reduced chromium as the cocatalyst and kaolin as the carrier is charged into the reactor. Then pass into acetaldehyde at the space velocity of 0.03-0.15L•h-1 and control the ratio of hydrogen and acetaldehyde being 5: 1 and the ratio of ammonia and acetaldehyde being 0.4-3:1. The feedstock is vaporized and fed to the reactor at 80℃. The reaction temperature is controlled between 105 and 200 °C. The resulting product is cooled at-5°C and separated into ethylamine, diethylamine and triethylamine. Ethylamine is more readily available because of the faster formation of ethylamine than diethylamine or triethylamine. When the primary product is diethylamine or triethylamine, the resulting ethylamine should be recycled to the system for reaction.
3. The preparation method is ethanol gas phase amination. The reaction of ethanol and ammonia with the catalysis at the temperature of 390-400 °C and under the pressure of 2.53~3.04 MPa can produce crude ethylamine, and then the finished products can be derived by further fractionation.

General Description

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.

Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

Sensitive to heat. Reacts vigorously with oxidizing agents. Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. 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 .

Health Hazard

Inhalation causes irritation of respiratory tract and lungs; pulmonary edema may result. Liquid causes severe irritation and burns of eyes and skin, and can permanently injure eyes after 15 seconds' contact. Ingestion causes severe burns of mouth and stomach; can be fatal.
