Definition

Noun: A colorless, odorless, sweet-tasting, syrupy organic compound that is highly toxic. It is a diol (a molecule with two hydroxyl groups) primarily used as an antifreeze in cooling and heating systems, and as a raw material in the manufacture of polyester fibers and resins.

Usage

"Ethylene glycol" is a technical and chemical term. It is used as a mass noun (uncountable) in industrial, automotive, and chemical contexts to refer to the substance itself. * It is commonly found in the compound term ethylene glycol antifreeze. * In medical contexts, it is referred to in cases of accidental or intentional poisoning.

Examples

• Industrial/Chemical Use:
  • The factory uses ethylene glycol as a precursor for producing PET plastic.
  • This coolant is a 50/50 mixture of ethylene glycol and water.
• Safety Context:
  • Ingestion of ethylene glycol can lead to severe kidney damage and is often fatal if not treated promptly.
  • Keep containers of ethylene glycol away from pets, as its sweet taste attracts them.

Advanced Usage

• Chemical Properties: In chemistry, "ethylene glycol" (HOCH₂CH₂OH) is the simplest member of the glycol family. Its key properties are its low freezing point when mixed with water and its high boiling point.
• Regulatory Context: Its handling and disposal are often subject to environmental and safety regulations due to its toxicity.

Variants and Related Words

• Antifreeze (n): A fluid, often based on ethylene glycol or propylene glycol, used to lower the freezing point of a liquid.
• Monoethylene glycol (MEG) (n): Another name for ethylene glycol, commonly used in the chemical industry.
• Diethylene glycol (n): A chemically related compound with different properties and toxicity.
• Propylene glycol (n): A less toxic glycol often used as a safer alternative in applications where contact with humans or animals is possible (e.g., food, pharmaceuticals).

Synonyms

• 1,2-ethanediol (n): The systematic IUPAC name for ethylene glycol.
• MEG (n): A common industrial abbreviation for monoethylene glycol.
