What is ethylene glycol 107-21-1?
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol) with the formula (CH 2OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid.

What is mono ethylene glycol used for?
A primary industry use of mono ethylene glycol is in antifreeze applications where it is a component in the manufacture of antifreeze, coolants, aircraft anti-icers and deicers due to its ability to depress the freezing temperature of the water.
| Properties of MEG | Applications/Uses of MEG |
| Chemical Intermediate for Resins | · Polyester resins (fibers, containers, and films) · Resin esters as plasticizers (adhesives, lacquers, and enamels) · Alkyd-type resins (synthetic rubbers, adhesive & surface coatings) |
| Solvent Coupler | · Stabilizer against gel formation · Freezing point depression · Heat transfer fluids (gas compressors, heating, ice rinks etc) · Al weather anti-freeze and as coolants · Water-based formulation (adhesives, latex paints, asphalt emulsions) |
| Solvent | Medium for suspending conductive salt in electrolytic capacitors. |
| Humectants | · Textile Fibers · Paper & Leather · Adhesives & Glue |
| Chemical Intermediate | Used as Solvents. |
Are ethylene glycol and mono-ethylene glycol the same?
Chemical Structure
Ethylene glycol(CAS 107 21 1) and monoethylene glycol differ significantly in their chemical structures. Ethylene glycol is a diol with the chemical formula CH₂OHCH₂OH, consisting of two hydroxyl groups (-OH) and two carbon atoms. In contrast, monoethylene glycol is a monohydric alcohol with the formula HOCH₂CH₂OH, containing only one hydroxyl group and two carbon atoms.
Applications
The uses of ethylene glycol and meg ethylene glycol also vary. Ethylene glycol is widely used in the production of polyester, solvents, lubricants, and antifreeze. Monoethylene glycol, on the other hand, is mainly used in the manufacture of resins, coatings, paints, cleaning agents, and emulsifiers.
Toxicity
There is also a difference in toxicity between the two. Ethylene glycol is a toxic substance that can cause poisoning and even death. It can be absorbed by the human body and metabolized into oxalic acid, leading to metabolic acidosis. Monoethylene glycol is relatively less toxic and has a lower impact on human health.
Conclusion
In summary, although ethylene glycol and meg glycol have similar names, they differ greatly in chemical structure, applications, and toxicity. The appropriate material should be selected based on specific needs to avoid harm to both human health and the environment.
