Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
Ethylene glycol (EG) fluids are still in use for aircraft deicing in some parts of the world because it has a lower operational use temperature (LOUT) than propylene glycol (PG). However, PG is more common because it is less toxic than ethylene glycol. [6]: 2–29 [2]
^2 Includes mono- and di- ethers of ethylene glycol, diethylene glycol, and triethylene glycol R−(OCH 2 CH 2) n −OR' where; n = 1, 2, or 3 R = alkyl C7 (chain of 7 carbon atoms) or less; or phenyl or alkyl substituted phenyl R' = H or alkyl C7 or less; or OR' consisting of carboxylic acid ester, sulfate, phosphate, nitrate, or sulfonate.
Ethylene glycol has a bitter, sweet taste and causes inebriation. The toxic effects of ingesting ethylene glycol occur because it is converted by the liver into 4 other chemicals that are much more toxic. The lethal dose of pure ethylene glycol is 1.4 ml/kg (3 US fluid ounces (90 ml) is lethal to a 140-pound (64 kg) person) but is much less ...
Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system. The waste TEG produced by this process has been found to contain enough benzene to be classified as hazardous waste [3] (benzene concentration greater than 0.5 mg/L).
DeCarlo said nearly all the readings were higher than 11 parts of ethylene oxide per 1 trillion parts of air — a level that translates to a one in 10,000 cancer risk for long-term exposure to ...

A former Air Force base responsible for potentially exposing hundreds of thousands to toxic chemicals is now a desolate wasteland that has remained abandoned in California for 32 years.
