What Is the Difference Between Monoethylene Glycol and Diethylene Glycol?
Monoethylene glycol (MEG) and diethylene glycol (DEG) are both ethylene glycols, but they differ in chemical structure, applications, and market demand. Understanding these differences helps buyers select the correct product for industrial use.
Basic Chemical Differences
Monoethylene Glycol is the simplest form of ethylene glycol, while Diethylene Glycol has a larger molecular structure formed by two ethylene glycol units.
| Item | Monoethylene Glycol (MEG) | Diethylene Glycol (DEG) |
|---|---|---|
| CAS Number | 107-21-1 | 111-46-6 |
| Molecular Formula | C₂H₆O₂ | C₄H₁₀O₃ |
| Molecular Weight | 62.07 g/mol | 106.12 g/mol |
| Typical Purity | ≥99.8% | ≥99.5% |
Differences in Applications
MEG is mainly used in PET resin, polyester fiber, antifreeze, and engine coolants, making it the most widely traded glycol worldwide.
DEG is commonly used in unsaturated polyester resins, plasticizers, solvents, and lubricants, with lower overall market volume.
