What is ethylene glycol CAS 107-21-1?

Ethylene glycol is a colorless, odorless liquid at room temperature. Ethylene glycol is widely used as antifreeze and engine coolant, as an ingredient in the manufacture of plastics and resins, and in the pharmaceutical and cosmetics industries.

Common synonyms: Ethane-1,2-diol, Ethylene alcohol, Monoethylene glycol, 1,2-Dihydroxyethane

Product: ethylene glycol EG

CAS: 107-21-1

Structure:

Properties of ethylene glycol (EG CAS 107-21-1)

• Reactivity: Ethylene glycol is a reactive chemical compound that can react violently with strong oxidizing agents.
• Melting point: The melting point of CAS 107-21-1 is around -13 degrees Celsius.
• Solubility: It is miscible with water, alcohol and many organic solvents.
• Health risks: Mono ethylene glycol (MEG) can be toxic if swallowed, inhaled or in contact with the skin. It can cause irritation, kidney and liver damage, and even death if ingested in large quantities.

What is ethylene glycol (EG CAS 107-21-1) used for?

1. Primary Industrial Uses

• Polyester Production (65%): The dominant use as a precursor for Polyethylene Terephthalate (PET), found in textiles (polyester fiber), plastic bottles, and films.
• Antifreeze and Coolants (20%): Its ability to significantly lower the freezing point and raise the boiling point of water makes it ideal for automotive engine coolants, de-icing fluids for aircraft and runways, and heat-transfer fluids in HVAC systems.
• Chemical Intermediate and Solvents (8%): Ethylene glycol (CAS 107-21-1) is used to produce glycol ethers, plasticizers, resins (alkyd, unsaturated polyester), and as a solvent in paints, inks, dyes, and industrial cleaners. Also used in hydraulic and brake fluids.

2. Other Applications

• Gas Dehydration: CAS 107-21-1 MEG is used to remove water vapor from natural gas streams and to suppress hydrate formation in pipelines.
• Other Niche Uses: Humectant in paper/tobacco, carrier for fragrances and explosives, component in electrolytic capacitors, and cryoprotectant for biological specimen preservation.
