Mono ethylene Glycol (MEG)

Monoethylene glycol (MEG) is an organic compound with the molecular formula C2H6O2. It is a colorless, odorless, and sweet-tasting liquid that is miscible with water and many organic compounds.

 

Physical Properties:

  • Colorless and odorless liquid
  • Slightly viscous
  • Sweet taste (Important: Do not ingest!)
  • Miscible with water and many other organic compounds
  • Melting point: -12.9 °C
  • Boiling point: 197-198 °C

Monoethylene glycol is a key player in many industries.

  • Plastic Production: MEG is a crucial building block for polyester resins, fibers (like those in clothing), and polyurethanes. It’s also an essential material for PET, the plastic widely used in beverage bottles.
  • Temperature Control: MEG’s ability to withstand varying temperatures makes it valuable as an antifreeze additive in engines, machines, and air conditioning systems. Heat pumps and airport de-icing equipment also rely on MEG for its heat transfer properties.
