Description

Functional Role and Intended Users in Industrial Chemistry

Monoethanolamine (MEA) is engineered as a multi-functional intermediate for industrial users requiring high-purity absorption and synthesis capabilities. Primarily targeted at petrochemical processors, gas treatment plants, and specialty chemical manufacturers, MEA effectively absorbs acidic gases like CO₂ and H₂S, supporting environmental compliance and operational efficiency. Furthermore, as a foundational raw material, it enables the production of surfactants and emulsifiers critical to industrial cleaners, extending also into pharmaceutical and agrochemical intermediate applications. Our status as a reputable mtbe solvent manufacturer ensures consistent supply and quality standards aligned with demanding industrial processes.

Produced through a controlled reaction of ethylene oxide with ammonia followed by precise distillation, this Monoethanolamine product boasts a purity ≥99.0%, with a molecular formula C₂H₇NO ensuring chemical stability and reactivity. It presents as a colorless to slightly yellow syrupy liquid, fully miscible with water and exhibiting alkaline properties essential for neutralizing acidic compounds. Physical parameters include a boiling point of 170.9 °C and viscosity of 24.1 mPa·s at 20 °C. These specifications affirm its applicability in continuous gas scrubbing systems and chemical synthesis lines. The product’s corrosive and hygroscopic nature requires dedicated safety protocols, emphasizing our role as a dependable mtbe manufacturer and chemicals supplier committed to stringent quality control and safe handling.


Applications and Industry Integration for Process Efficiency

MEA’s versatility underpins its deployment across multiple sectors including petroleum refining for acidic gas desorption, natural gas conditioning, textile chemical manufacturing, and metalworking fluid formulation. It functions as a key reactant in producing surfactants used by industrial cleaners, while also serving as a pH regulator and corrosion inhibitor. The product’s integration into cyclical absorption-desorption systems enhances operational sustainability and cost-effectiveness. Clients engaged in chemical processing and environmental management value MEA’s consistent supply from an experienced mtbe solvent manufacturer, enabling seamless integration into complex workflows and compliance-driven production environments.




Product Advantages


Design and Structural Benefits Supporting Industrial Processes

The chemical structure of Monoethanolamine, combining amine and alcohol functional groups, offers dual reactive sites facilitating broad compatibility with acidic gases and synthetic pathways, a clear advantage for industrial cleaners’ formulations. Manufactured through an optimized distillation process, the design yields minimal impurities which directly translates into enhanced system longevity and reduced fouling in gas treatment units. Our capability as a leading mtbe solvent manufacturer provides clients with large-scale, stable product availability aligned with industrial demand cycles. The modular nature of its application allows integration into diverse chemical production lines, reinforcing operational scalability and process reliability.


Performance Strength and User-Oriented Value Proposition

Monoethanolamine delivers high absorption efficiency and chemical stability under variable operational conditions, enabling improved ROI through extended equipment lifespan and reduced maintenance needs. Its complete water miscibility ensures effortless incorporation into existing aqueous process streams utilized by chemicals suppliers and industrial end-users alike. The product’s alkaline character supports neutralization and corrosion inhibition, enhancing safety and compliance. User value is further driven by its adaptability in synthesizing specialty surfactants and solvents like those required by mtbe chemical operations, providing versatility across multiple chemical manufacturing sectors.


Monoethanolamine (abbreviated as MEA, CAS No.: 141-43-5) is produced by substituting one hydrogen atom in ammonia with a hydroxyethyl group, making it a primary amine. Its molecule contains both a basic amino group and a hydrophilic hydroxyl group, enabling it to react with acids to form salts and conferring good water solubility and hygroscopicity. In gas purification, its aqueous solutions are widely used in petroleum refining, natural gas processing, and synthetic ammonia industries to remove acidic gases (e.g., CO₂, H₂S) from process gases, favored for their strong absorption capacity and ability to be regenerated by heating for cyclic use. As a chemical intermediate, it is a key raw material for synthesizing nonionic surfactants (e.g., alkanolamides), emulsifiers, and corrosion inhibitors. In personal care and pharmaceuticals, it is used to prepare conditioning agents in cosmetics and shampoos, and to synthesize certain drugs (e.g., ethambutol for tuberculosis treatment). As an industrial additive, it serves as a softening agent for textiles and as a pH regulator and anti-rust additive in metalworking fluids. Our product, manufactured in Shandong, China, is produced via the mature process of reacting ethylene oxide with ammonia followed by distillation, achieving a purity of ≥99.0% with low levels of other ethanolamine impurities (diethanolamine, triethanolamine) and stable quality. This product is corrosive and hygroscopic, and causes irritation to eyes, skin, and the respiratory tract. Protective equipment must be worn and forced draft ventilation ensured during handling.
