A scientist carefully pours ethanediol into a beaker in the laboratory.

Definition
  1. Noun:
    • A sweet but poisonous syrupy liquid used as an antifreeze and solvent: Ethanediol is a colorless, viscous, hygroscopic liquid with a sweet taste. It is a diol (an alcohol containing two hydroxyl groups) and is a key ingredient in automotive antifreeze and coolant formulations. Its toxicity is a significant hazard, as ingestion can be fatal.
Usage Examples
  • Noun:
    • The mechanic warned that ethanediol, while effective, must be handled with care due to its toxicity.
    • Ethanediol is a common component in de-icing fluids for aircraft.
Advanced Usage
  • Chemical Context: In industrial and chemical terminology, "ethanediol" is the systematic IUPAC name, emphasizing its structure as a two-carbon chain with alcohol groups on each end. It is often discussed in contexts of organic synthesis, polymer production (e.g., polyethylene terephthalate for plastics and fibers), and as a humectant.
    • The production of this polyester requires ethanediol as a monomer.
Variants and Related Words
  • Ethylene glycol: This is the most common industrial and commercial name for ethanediol. The terms are often used interchangeably, though "ethanediol" is more formal.
    • Most automotive antifreeze is based on ethylene glycol.
  • Monoethylene glycol (MEG): A technical name used in the chemical industry to distinguish it from diethylene or triethylene glycol.
  • 1,2-ethanediol: A precise synonym specifying the position of the hydroxyl groups on the carbon chain.
Synonyms
  • Ethylene glycol: The primary synonym.
  • 1,2-ethanediol: A systematic chemical synonym.
  • MEG: An acronym used in industrial contexts.
Related Phrases / Compound Terms
  • Ethanediol poisoning: Refers to the medical condition resulting from ingestion of the substance.
    • Symptoms of ethanediol poisoning can resemble alcohol intoxication initially.
  • Ethanediol-based antifreeze: A descriptive term for the most common application.
    • Ethanediol-based antifreeze lowers the freezing point of water in a car's cooling system.
