Ethylene glycol formula

Learning Objectives • To describe the structure and uses of some common polyhydric alcohols. Alcohols with two OH groups on adjacent carbon atoms are commonly known as glycols. The most important of these is 1,2-ethanediol (the common name is ethylene glycol), a sweet, colorless, somewhat viscous liquid. Another common glycol, 1,2-propanediol, is commonly called propylene glycol. Its physical properties are quite similar to those of ethylene glycol. Commonly called glycerol or glycerin, 1,2,3-propanetriol is the most important trihydroxy alcohol. Like the two glycols, it is a sweet, syrupy liquid. Glycerol is a product of the hydrolysis of fats and oils. Ethylene glycol is the main ingredient in many antifreeze mixtures for automobile radiators. The two OH groups lead to extensive intermolecular hydrogen bonding. This results in a high boiling point—198°C; thus ethylene glycol does not boil away when it is used as an antifreeze. It is also completely miscible with water. A solution of 60% ethylene glycol in water freezes at −49°C (−56°F) and thus protects an automobile radiator down to that temperature. Ethylene glycol is also used in the manufacture of polyester fiber and magnetic film used in tapes for recorders and computers. To Your Health: Glycols and Human Health Ethylene glycol is quite toxic. Because it is sweet, pets often lap up spills of leaked antifreeze from a garage floor or driveway. Sometimes people, especially children, drink it. As with methanol, its toxi...

Ethylene Glycol Ethylene glycol is a colorless, sweet-tasting liquid that is used as an anti-freeze, in the manufacture of polyester fibers and films, as a heat-transfer fluid, in aircraft and runway de-icing mixtures, to provide freeze-thaw stabilization to latex coatings, to improve the flexibility and drying time of paints, as a dehydrating agent in natural gas, in motor oil additives, as an additive in inks, pesticides, wood stains, and adhesives, and as a solvent and suspending medium for ammonium perborate, the conductor in most electrolytic capacitors.

Devlin, M. Schwartz, in Encyclopedia of Toxicology (Third Edition), 2014 Background Ethylene glycol was first synthesized in 1859; however, it did not become a public health concern until after World War II. In fact, the first published series of deaths from ethylene glycol consumption involved 18 soldiers who drank antifreeze as a substitute for ethanol. Despite the early recognition that patients who drank ethanol in addition to ethylene glycol had prolonged survival when compared to those drinking ethylene glycol alone, antidotal treatment of ethylene glycol toxicity with ethanol was not evaluated until the 1960s. Today, ethylene glycol poisoning continues to be a public health problem, ...
