Di Ethanol Amine (DEA)
Di Ethanol Amine (DEA)
Chemical Formula: C₄H₁₁NO₂
Physical Form: Liquid
Supplier: Shazand Petrochemical Company (Iran)
Packaging: Standard industrial barrelsMonoethanolamine (MEA) is a clear, colorless, hygroscopic liquid widely used as a chemical intermediate and gas treatment agent. Produced by Shazand Petrochemical Company, this compound exhibits both amine and alcohol functionality, enabling it to react with acids to form salts or with esters to produce ethanolamides.
In industrial use, MEA is primarily applied in gas sweetening processes (for the removal of CO₂ and H₂S from natural gas and refinery streams), as well as in detergents, emulsifiers, pharmaceuticals, and surface-active agents. Its strong alkalinity and solvent properties make it a valuable material across chemical, petrochemical, and agro-industrial applications.
Key Features
High reactivity due to dual amine and alcohol groups
Excellent CO₂ and H₂S absorption efficiency
Effective emulsifying and cleaning agent
Good solubility in water and organic solvents
Suitable for industrial, chemical, and gas treatment applications
Diethanolamine (DEA) is an organic chemical compound produced through the reaction between ammonia and ethylene oxide. It is a hygroscopic material that can appear as either a colorless to pale-yellow liquid or a waxy solid, depending on temperature and purity.
At room temperature, DEA exhibits low volatility and a characteristic ammoniacal odor. The compound possesses both amine and alcohol functional groups, giving it excellent reactivity and solvent properties. This dual functionality allows DEA to act as a surfactant, emulsifier, and chemical intermediate in various industrial applications.
Diethanolamine is widely used in the production of gas treatment chemicals, cosmetic formulations, detergents, pharmaceuticals, and textile finishing agents. Its ability to react with fatty acids and other reagents enables the creation of ethanolamides, which serve as key ingredients in personal care and cleaning products.
Key Features
Produced from ammonia and ethylene oxide
Low volatility and hygroscopic behavior
Characteristic ammoniacal odor
Solid or liquid form depending on temperature and purity
Excellent reactivity for surfactant and gas treatment formulations
Low Volatility at Room Temperature:
Diethanolamine (DEA) exhibits low vapor pressure and minimal volatility under ambient conditions, ensuring safe handling and reduced evaporative loss during storage and processing. This property makes DEA ideal for closed-system industrial applications, such as gas sweetening, chemical synthesis, and formulation of surfactants and detergents.
Its low volatility contributes to improved process stability and longer shelf life, particularly in formulations requiring controlled moisture content or consistent concentration.
