In the realm of industrial chemistry, certain compounds stand out for their versatility and broad applicability. 2-Aminoethanol, commonly known as Monoethanolamine (MEA) or by its CAS number 141-43-5, is one such compound. Possessing both an alcohol (hydroxyl) and an amine (amino) functional group, MEA exhibits a unique chemical reactivity that makes it indispensable across a wide spectrum of industries. This article aims to provide a comprehensive overview of its key properties, reactions, and diverse industrial uses, highlighting why sourcing high-quality MEA from reliable manufacturers is essential.

Chemical Structure and Properties

2-Aminoethanol (C2H7NO) is a simple molecule featuring a primary amine group and a primary alcohol group separated by an ethyl chain: HO-CH2-CH2-NH2. This bifunctional nature dictates its chemical behavior:

  • Physical State: It is a colorless, viscous liquid at room temperature with a distinct, ammonia-like odor.
  • Solubility: MEA is highly miscible with water, alcohols, and other polar solvents, but has limited solubility in non-polar solvents like ether and benzene.
  • Reactivity: The presence of the amine group makes MEA a weak base, capable of reacting with acids to form salts. The hydroxyl group allows it to undergo reactions typical of alcohols, such as esterification and etherification.
  • Hygroscopic Nature: MEA tends to absorb moisture from the air, necessitating proper storage in tightly sealed containers.

Key Industrial Applications Driven by Reactivity

The dual functionality of MEA underpins its extensive use:

  • Gas Treatment (Sweetening): MEA is a primary absorbent for removing acidic gases like CO2 and H2S from natural gas, refinery gases, and flue gas. Its ability to reversibly react with these gases makes it ideal for purification processes.
  • Chemical Synthesis: As a foundational intermediate, MEA is used to synthesize a vast array of other chemicals. It’s a precursor for ethyleneamines, which are critical in producing chelating agents like EDTA. It also forms surfactants, emulsifiers, and is used in the production of pharmaceuticals, dyes, and agrochemicals.
  • Formulation Additive: In detergents and personal care products, MEA acts as a pH adjuster, emulsifier, and precursor for surfactants. In pharmaceuticals, it serves as a buffering agent and in certain injectable formulations.
  • Corrosion Inhibition: MEA is added to various industrial water systems and coolants to help prevent metal corrosion.
  • Leather and Textile Auxiliaries: It's employed as a softening agent for leather and as a processing aid in textile dyeing and finishing.

Sourcing Considerations for MEA

For businesses looking to purchase 2-Aminoethanol, ensuring quality and a stable supply is paramount. When selecting a manufacturer, consider:

  • Purity and Specifications: Verify that the MEA meets the required purity (e.g., 97% min) and has minimal undesirable by-products.
  • Manufacturing Capabilities: Choose a supplier with robust production capacity and adherence to quality management systems.
  • Logistics and Distribution: A reliable partner will offer efficient shipping options and global reach.
