Aminoethanol or monoethanolamine (often referred to as ETA or MEA) is an organic compound that is both an alcohol and an amine. Monoethanolamine is produced from the reaction of ethylene oxide with liquid ammonia. Uses: Monoethanolamine or MEA is used to absorb certain acidic gases in the liquid state. MEA is also used as a primary ingredient in the production of detergents, emulsifiers, glosses, drugs, anti-corrosion agents and chemical intermediates.

Monoethanolamine is produced from the reaction of ethylene oxide with liquid ammonia. This reaction also produces monoethanolamine ethanolamine and triethanolamine. The ratio of the production of different products is adjustable by the steady state change of the reaction. This reaction was warm and should prevent the temperature from rising and reaching the ignition point.
This liquid can cause severe irritation with symptoms of redness, swelling and burn in the eye. It has a very low toxicity from the digestive tract, but it can cause severe irritation. Inhalation of this substance at high concentrations can cause severe pulmonary damage. This liquid is combustible and can cause an explosion at temperatures above 85 ° C.
