Monoethanolamine (MEA) - A Versatile Chemical Intermediate

Monoethanolamine (MEA), also known as 2-aminoethanol, is a clear, viscous, and hygroscopic liquid with a faint ammoniacal odor. It's a primary alkylamine, meaning it contains a single amino group (-NH2) attached to a primary carbon atom. This chemical structure gives MEA its unique properties, making it a crucial component in various industrial applications.

Chemical Formula: HOCH₂CH₂NH₂

CAS Number: 141-43-5

Key Properties:

• Appearance: Colorless to light yellow viscous liquid
• Odor: Faint ammoniacal odor
• Solubility: Miscible with water, ethanol, and many other organic solvents.
• Boiling Point: 170-171 °C (338-340 °F)
• Melting Point: 10.5 °C (50.9 °F)
• Density: Approximately 1.01 g/cm³
• pH (10% aqueous solution): Approximately 10.5-11.5
• Reactivity: Reacts with acids to form salts, and with various other chemicals to create a wide range of derivatives.

Applications:

MEA's versatility stems from its ability to act as both a base and a nucleophile. This makes it indispensable in a variety of industries, including:

• Gas Treating: This is perhaps the most significant application of MEA. It's widely used in the removal of acid gases (like carbon dioxide and hydrogen sulfide) from natural gas, refinery streams, and other industrial processes. Its strong basicity allows it to readily absorb these acidic gases, leading to cleaner and more valuable products.
• Chemical Intermediate: MEA serves as a building block for the synthesis of a vast array of chemicals, including:
  • Surfactants: Used in detergents, emulsifiers, and wetting agents.
  • Pharmaceuticals: Utilized in the production of various medications and pharmaceutical intermediates.
  • Cosmetics: Employed in the formulation of various skin care products and hair care products.
  • Corrosion Inhibitors: Protecting metal surfaces from corrosion.
  • Polymers: Used in the synthesis of certain polymers and resins.
  • Agricultural Chemicals: Found in herbicides and other agrochemicals.
• Other Applications:
  • pH adjustment: In various industrial processes and formulations.
  • Solvent: In certain specialized chemical reactions.
  • Emulsifier: In some food and cosmetic applications.

Safety Precautions:

MEA is a moderately hazardous chemical and should be handled with care. It is corrosive and can cause skin and eye irritation. Appropriate personal protective equipment (PPE), including gloves, goggles, and lab coats, should be worn during handling. Consult the Safety Data Sheet (SDS) for detailed safety information and proper handling procedures.

Packaging and Storage:

MEA is typically supplied in various packaging options, including drums, IBC totes, and tank trucks. It should be stored in a cool, dry, well-ventilated area, away from incompatible materials.
