Diethanolamine, an organic
The name of the substance (Persian): De Ethanol Amine
The name of the substance (English): Di-ethanolamine
Brand (Farsi): Diethylamine
Brand name: DEA
Other names: N-N-di-ethyl-amine, di (2-hydroxyethyl), DELA, DEA, two (hydroxyethyl) amine, amine, diolamine-
Related Materials: Ethanol Amine
Production complexes: Arak Petrochemical Complex
This substance is colorless and of several properties, because it is both amine and a di. Like other organic amines, diethylene amine is a weak one. The properties of water are alcohols and are soluble in water. The amides prepared from DEA also have hydrophilic properties. Other ethane-amine derivatives include
Diethanolamine or DEA are used as surfactants or anti-corrosion agents. It is also used to remove carbon dioxide and hydrogen sulfide.

The reaction of ethylene oxide with an ammonia solution initially produces ethanolamine: C2H4O + NH3-H2NCH2CH2OH reacts with two or three ethylene oxides and produces DEA and triethanolamine: C2H4O + H2NCH2CH2OH-HN (CH2CH2OH) 2 C2H4O + HN (CH2CH2OH) 2- N (CH2CH2OH) 3 An average of about 300M kg of diethanolamine is produced annually in this way. The production ratio of the products can be controlled by changing the stoichiometric ratio.
This material and its solubility in contact with skin and eyes can cause severe irritation with discomfort, pain and burn. The ingestion of this substance causes severe burns and burns with nausea. Diethanolamine may become nitrosamine, which is a very carcinogenic substance.
