What is a DEA (diethanolamine 111-42-2 ) used for?

, also known as 2,2'-dihydroxydiethylamine or iminodiethanol, abbreviated as DEA, is an organic compound. It is a colorless, viscous liquid at room temperature with a slight ammonia odor and is readily soluble in water and ethanol. It can corrode copper, aluminum, and their alloys. It can react with various acids to form esters and amide salts. Its boiling point is 268.4℃, and its melting point is 28℃. It is mainly used in the production of the herbicide glyphosate and as a surfactant.

• DEA is used as a gas purifier, absorbing gases such as carbon dioxide and hydrogen sulfide from the air. It is widely used in the petroleum and natural gas industries.
• It is used as a corrosion inhibitor in drilling and cutting oils and other types of lubricating oils.
• DEA (diethanolamine 111-42-2) is used in boiler water treatment and as a coolant in automotive engines.
• It is used as an emulsifier in various cosmetics.
• In shampoos and light detergents, it is used as a thickener and foam improver.
• DEA (diethanolamine) is used as a lubricant in the textile industry, acting as a softener and lubricant. It also functions as a wetting agent, softener, and other raw materials for organic synthesis.
• It is used as a dye intermediate; in the synthesis of certain blue dyes, diethanolamine can be one of the reactants, thus producing high-quality dyes.
• DEA (diethanolamine) is used as a softener in the production of synthetic fibers and leather.
• In adhesives, it is used as an acid absorbent, plasticizer, softener, and emulsifier.
• In coatings, it is used as an auxiliary agent to adjust the viscosity and flowability of the coating, and to improve its adhesion and durability.
• DEA (diethanolamine 111-42-2) reacts with fatty acids to form alkylolamides.
• DEA (diethanolamine) is a raw material for the synthesis of pharmaceutical, pesticide, dye intermediates, and surfactants.
• In car wash liquids, it is used as a detergent, polishing agent, lubricant, softener, and surfactant. As a rust inhibitor, it reacts with metal surfaces to form a protective film, preventing oxidation and corrosion.
• It is used as a crosslinking agent in the production of high-resilience polyurethane foam.
• As a concrete additive, it improves the crack resistance, early strength, and durability of concrete.
• Mixed with triethanolamine, it is used as a cleaning agent for aircraft engine pistons.
• It is used as a complexing agent for silver, cadmium, lead, and zinc plating.
• DEA (diethanolamine 111-42-2) is used as an analytical reagent and a stationary phase in gas chromatography.
• As a plant growth regulator, it promotes root and leaf development, increasing photosynthetic capacity and yield.
