Ethylene glycol (Eg CAS 107-21-1) has some antifreeze properties, but its effectiveness is limited.
How effective is the antifreeze performance of ethylene glycol (Eg CAS 107-21-1)?
Ethylene glycol is a common antifreeze raw material with excellent basic chemical properties, exhibiting good antifreeze and anti-thermal oxidation properties. Adding an appropriate amount of ethylene glycol to water can prevent it from freezing at low temperatures. Studies have shown that a 50% concentration of ethylene glycol will not freeze at -34.5℃. Therefore, ethylene glycol can be used as an effective antifreeze agent.
What are the antifreeze applications of ethylene glycol (Eg CAS 107-21-1)?
Ethylene glycol is widely used in automobiles, aircraft, generator sets, buildings, and chemical equipment to prevent water from freezing at low temperatures, thereby protecting the normal operation of equipment and systems. In addition, EG can be used as a solvent for certain mixtures and as an additive in the production processes of cosmetics and pharmaceuticals.

Main uses of 1,2-ethanediol (ethylene glycol)
Ethylene glycol has a wide range of uses, including:
- Primarily used as a solvent, antifreeze, and raw material for synthetic polyester.
- Aqueous solutions of MEG have a very low freezing point, so it is used as an antifreeze agent.
- MEG can be mixed with water in any proportion. After mixing, the vapor pressure of the cooling water is altered, significantly lowering the freezing point and maintaining good antifreeze properties at low temperatures. Therefore, it is widely used in coolants for automobile and aircraft engines.
- 1,2-ethanediol (ethylene glycol) can also be used as a wetting agent in cellophane, fibers, leather, and adhesives.
