Description

Monoethanolamine CAS NO 141-43-5 is a versatile amino alcohol and a key organic intermediate with a unique combination of amine and alcohol functional groups. This bifunctional nature makes it an essential building block for numerous industrial processes, offering both basicity and reactivity. It is a critical raw material for manufacturers in the agrochemical, pharmaceutical, personal care, and gas treatment industries, where its properties as a neutralizing agent, absorbent, and chemical precursor are highly valued.

Application

• Gas Scrubbing & Treatment: Primarily used as an absorbent for the removal of acidic gases like carbon dioxide (CO₂) and hydrogen sulfide (H₂S) in natural gas processing and refinery operations.
• Surfactant & Emulsifier Production: A fundamental component in the synthesis of fatty acid alkanolamides and ethoxylates, which are key ingredients in detergents, shampoos, and industrial cleaners.
• Chemical Intermediate: Serves as a crucial precursor for the manufacture of ethyleneamines, chelating agents (e.g., EDTA derivatives), and various pharmaceutical active ingredients.
• Agrochemical Formulations: Used in the production of herbicides, fungicides, and pesticides, often as a salt-forming agent or a component in emulsifiable concentrates.
• Corrosion Inhibition: Employed in metalworking fluids and boiler water treatment formulations to neutralize acids and protect metal surfaces.
• Cement Grinding Aid: Acts as an additive to improve the efficiency of the cement milling process and enhance the quality of the final product.
• Textile & Leather Processing: Utilized in dyeing and finishing processes, as well as in the production of leather softeners and fatliquoring agents.

Quality Control

Our Monoethanolamine is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including Industrial and High-Purity, to meet diverse application needs. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, water content, and impurity profiles. Our quality commitment aligns with major international standards, and we can provide material tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
