Diethylene glycol is used in the manufacture of saturated and unsaturated polyester resins, polyurethanes, and plasticizers. DEG is a precursor to morpholine and 1,4-dioxane. It is a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds. It is a humectant for tobacco, cork, printing ink, and glue. [7]
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 1985 Austrian diethylene glycol wine scandal (German: Glykolwein-Skandal) was an incident in which several Austrian wineries illegally adulterated their wines using the toxic substance diethylene glycol (a minor ingredient in some brands of antifreeze) to make the wines taste sweeter and more full-bodied in the style of late harvest wines.

It is more volatile than glycol. [1] Once used for automotive antifreeze, glycerol has the advantage of being non-toxic, withstands relatively high temperatures, and is noncorrosive. It is not however used widely. [1] Glycerol was historically used as an antifreeze for automotive applications before being replaced by ethylene glycol.
It is usually used with additives, like corrosion inhibitors and antifreeze. Antifreeze, a solution of a suitable organic chemical (most often ethylene glycol, diethylene glycol, or propylene glycol) in water, is used when the water-based coolant has to withstand temperatures below 0 °C, or when its boiling point has to be raised.
Four thousand years of winemaking history counted for little after the "antifreeze scandal" of 1985, when it was revealed that some wine brokers had been adulterating their wines with diethylene glycol. The scandal destroyed the market for Austrian wine and compelled Austria to tackle low standards of bulk wine production, and reposition itself ...
Deicing a Boeing 737 with Type I fluid A layer of Type IV anti-icing fluid. De-icing fluids come in a variety of types, and are typically composed of ethylene glycol (EG) or propylene glycol (PG), along with other ingredients such as thickening agents, surfactants (wetting agents), corrosion inhibitors, colors, and UV-sensitive dye.
Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available, and are generally considered safer to use, as it possesses an unpleasant taste in contrast to the perceived "sweet" taste of toxic ethylene glycol-based coolants, and produces only lactic acid in an animal's body, as their muscles do ...
