[1900-05]

* * *

Simplest member of the glycol family, also called 1,2-ethanediol (HOCH₂CH₂OH).

It is a colourless, oily liquid with a mild odour and sweet taste. Widely used as an antifreeze in automobile cooling systems, it is also used in many other chemical processes. It and some of its derivatives are fairly toxic. Many dogs, cats, and wild animals are attracted by its sweetness and poisoned by drinking ethylene glycol antifreeze that has been carelessly discarded.

also called  ethane-1,2-diol 

      simplest member of the glycol family of organic compounds (organic compound). A glycol is an alcohol with two hydroxyl groups on adjacent carbon atoms (a 1,2-diol). The common name ethylene glycol literally means “the glycol derived from ethylene.”

      Ethylene glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C (388.4 °F). Its most common use is as an automotive antifreeze. A 1:1 solution of ethylene glycol and water boils at 129 °C (264.2 °F) and freezes at −37 °C (−34.6 °F), serving as an excellent coolant in automotive radiators. Ethylene glycol is highly poisonous; animals or humans that drink the solution become very ill and may die.

      In addition to its use in antifreeze, ethylene glycol is used as an ingredient in hydraulic fluids, printing inks, and paint solvents. It is also used as a reagent in making polyesters (polyester), explosives (explosive), alkyd resins (resin), and synthetic waxes (wax).
