Is Ethylene Glycol the Same as Monoethylene Glycol?
Yes, ethylene glycol (EG) and monoethylene glycol (MEG) are essentially the same chemical substance. The difference primarily lies in terminology and application contexts.
What Is Ethylene Glycol?
Ethylene Glycol is an organic compound with the chemical formula C₂H₆O₂ and CAS No. 107-21-1. It is a clear, colorless liquid.
| C2H6O2 | Ethylene Glycol |
| Molecular Weight/ Molar Mass | 62.07 g/mol |
| Density | 1.11 g/cm³ |
| Boiling Point | 197.3 °C |
| Melting Point | -12.9 °C |
What Is Monoethylene Glycol (MEG)?
MEG Monoethylene Glycol refers specifically to the pure, single-molecule form of ethylene glycol, used to distinguish it from:
- Diethylene Glycol (DEG)
- Triethylene Glycol (TEG)
In global trade, MEG is the standard term used by manufacturers, exporters, and bulk buyers, especially in the polyester, PET resin, and chemical industries.
What Is Ethylene Glycol MEG Used for?
CAS 107-21-1 Ethylene Glycol MEG has a broad range of applications across multiple industries, with three core application directions. First, it is a key precursor for polyester fibers and polyethylene terephthalate (PET) resins, playing an irreplaceable role in the textile manufacturing and packaging material industries. Second, it is a main component of antifreeze and coolant, Mono Ethylene Glycol is widely used in engine and heating system temperature control. In addition, Ethylene Glycol MEG is also applied in the production of coatings, paints and synthetic resins as an important industrial raw material.
