Diethanolamine is a colorless and viscous liquid that is both a secondary amine and a diol. It is very soluble in water. Diethanolamine is produced by the reaction of ethylene oxide with excess ammonia.
Diethanolamine is widely used to produce dishwashing detergents, cosmetics, shampoos, and hair conditioners. Plus, DEA is used in textile processing, industrial gas purification, and in preparation of agricultural chemicals.
Characterization of Diethanolamine (DEA)
Pure Diethanolamine is a white solid at room temperature. Some properties of this substance include:
- Its molar mass is 1 g. mol-1.
- Its melting point is 27 °C.
- It is decomposed at 176 °C.
- Its density is 1.097 gcm–3
Applications of Diethanolamine (DEA)
Diethanolamine (DEA) is a secondary amine belonging to the class of ethanolamines. It acts as a surfactant and a corrosion inhibitor. Some uses of DEA include:
Agrochemicals
Diethanolamine with combining the properties of amines and alcohols in one molecule, is used for ph-neutralisation as well as a dilution agent. As an amine, it is mildly alkaline and reacts with acids to form salts or soaps. As an alcohol, diethanolamine can be transformed to ethers and esters.
Coatings
Diethanolamine is both an amine and a diol, and so it is used in the production of polymers. It is used to modify esters and aromatic epoxy resins.
Detergents
Diethanolamine is used as a building block, ph-neutralisation, as well as dilution-agent in the production of detergents.
Diethanolamine (DEA) production
Diethanolamine is produced by reacting ethylene oxide with ammonia. In most production lines, ethylene oxide and ammonia are reacted in a batch reactor that yields a mixture of ethanolamine, diethanolamine and triethanolamine.
Diethanolamine (DEA) storage
DEA should be kept away from incompatible materials. It should be stored only in the original container. DEA containers should be kept in a cool and well ventilated area.
Diethanolamine should be handled in accordance with good industrial hygiene and safety practices. When using DEA, do not eat, drink, or smoke. Plus, it is necessary to wash hands before breaks and at the end of work.
Diethanolamine stability
DEA should be stored protected from moisture and carbon dioxide, since diethanolamine is hygroscopic. If Diethanolamine stored sealed at room temperature, the product is expected to be show minimal change over several years.
Diethanolamine (DEA) health hazards
Diethanolamine is used in a number of products, such as shampoos, cosmetics, and pharmaceuticals. Immediately after exposure to DEA, the following short term health effects may occur:
- DEA contact can irritate and burn the skin and eyes.
- Inhaling DEA can irritate the nose and throat causing coughing.
- Exposure to DEA can cause headache, nausea, and vomiting.
