Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol ) with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid. Ethylene glycol … See more Industrial routes Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation See more Ethylene glycol has relatively high mammalian toxicity when ingested, roughly on par with methanol, with an oral LDLo = … See more • WebBook page for C2H6O2 • ATSDR - Case Studies in Environmental Medicine: Ethylene Glycol and Propylene Glycol Toxicity See more Coolant and heat-transfer agent The major use of ethylene glycol is as an antifreeze agent in the coolant in for example, … See more Ethylene glycol is used as a protecting group for carbonyl groups in organic synthesis. Treating a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst (e.g., p-toluenesulfonic acid; BF3·Et2O) gives the corresponding a 1,3-dioxolane, … See more Ethylene glycol is a high-production-volume chemical; it breaks down in air in about 10 days and in water or soil in a few weeks.
