[Chemical Properties]

Colorless to yellow liquid
[Uses]

Used as buffer; removal of carbon dioxide and hydrogen sulfide from gas mixtures.
[Definition]

ChEBI: A member of the class of ethanolamines that is ethane with an amino substituent at C-1 and a hydroxy substituent at C-2, making it both a primary amine and a primary alcohol.
[General Description]

A clear colorless liquid with an odor resembling that of ammonia. Flash point 185°F. May attack copper, brass, and rubber. Corrosive to tissue. Moderately toxic. Produces toxic oxides of nitrogen during combustion.
[Reactivity Profile]

ETHANOLAMINE(141-43-5) is a base. Reacts with organic acids (acetic acid, acrylic acid), inorganic acids (hydrochloric acid, hydrofluoric acid, nitric acid, sulfuric acid, chlorosulfonic acid), acetic anhydride, acrolein, acrylonitrile, cellulose, epichlorohydrin, mesityl oxide, beta-propiolactone, vinyl acetate. Emits toxic fumes of nitrogen oxides when heated to decomposition [Sax, 9th ed., 1996, p. 1498].
[Air & Water Reactions]

Water soluble with evolution of heat.
[Hazard]

Skin irritant.
[Health Hazard]

Vapor irritates eyes and nose. Liquid causes local injury to mouth, throat, digestive tract, skin, and eyes.
[Potential Exposure]

Monoethanolamine is widely used in industry for scrubbing acid gases and in production of detergents and alkanolamide surfactants; to remove carbon dioxide and hydrogen from natural gas, to remove hydrogen sulfide and carbonyl sulfide; as an alkaline conditioning agent; as an intermediate for soaps, detergents, dyes, and textile agents. Diethanolamine is an absorbent for gases; a solubilizer for 2,4- dichlorophenoxyacetic acid (2,4-D); and a softener and emulsifier intermediate for detergents. It also finds use in the dye and textile industry. Triethanolamine is used as plasticizers, neutralizer for alkaline dispersions; lubricant additive; corrosion inhibitor; and in the manufacture of soaps, detergents, shampoos, shaving preparations; face and hand creams; cements, cutting oils, insecticides, surface active agents; waxes, polishes, and herbicides.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material from skin is of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit
[Fire Hazard]

Hygroscopic (i.e., absorbs moisture from the air). Corrosive to copper, zinc, and galvanized iron (di-). The aqueous solution is a medium strong base. Attacks copper, zinc, aluminum, and their alloys.
[Waste Disposal]

Controlled incineration; incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions

[Description]

Ethanolamine is a kind of viscous hygroscopic amino alcohol contains both amine and alcohol chemical groups. It is widely distributed inside the body and is a component of lecithin. It has many kinds of industrial applications. For example, it can be used in the production of agricultural chemicals including ammonia as well as the manufacturing of pharmaceuticals and detergents. It can also be used as a surfactant, fluorimetric reagent and removing agent of CO2 and H2S. In pharmaceutical field, ethanolamine is used as a Vascular Sclerosing agent. It also has antihistaminic property, which alleviates the negative symptoms caused by H1-receptor binding.
