Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. [53] The reaction is catalyzed by acidic or basic catalysts. Ethylene glycol and its oligomers are preferable as a starting material instead of water because they allow the creation of polymers with a low ...
When ethylene glycol is used in a system, it may become oxidized to five organic acids (formic, oxalic, glycolic, glyoxalic and acetic acid). Inhibited ethylene glycol antifreeze mixes are available, with additives that buffer the pH and preserve alkalinity of the solution to prevent oxidation of ethylene glycol and formation of these acids.
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.
The main component of deicing fluid is a freezing point depressant (FPD), usually propylene glycol or ethylene glycol. Other ingredients vary depending on the manufacturer, but the exact composition of a particular brand of fluid is generally held as confidential proprietary information.
Ethylene glycol is a colorless, odorless, sweet liquid, commonly found in antifreeze. [1] It may be drunk accidentally or intentionally in a suicide attempt . [ 2 ] When broken down by the body it results in glycolic acid and oxalic acid which cause most of the toxicity.
Conventional cryoprotectants are glycols (alcohols containing at least two hydroxyl groups), such as ethylene glycol [citation needed], propylene glycol and glycerol. Ethylene glycol is commonly used as automobile antifreeze; while propylene glycol has been used to reduce ice formation in ice cream.
