Aqueous Diethanolamine (DEA) is a colorless organic liquid with an ammonia-like odor and is a bifunctional amine alcohol. Diethanolamine, like other amines, is a weak base and has the hydrophilic properties of alcohols and is soluble in water. Diethanolamine is used as a sweetening agent, surfactant or anti-corrosion agent. The advantage of using the chemical substance Diethanolamine compared to other amine compounds is not producing products such as CoS and CS2 and saving energy.
