Why would a motorist use ethylene glycol in his car
1985 diethylene glycol wine scandal recipe must have been drawn up by a knowledgeable wine chemist consulting for a large-scale producer. Diethylene glycol (DEG) was otherwise used as an industrial chemical or as antifreeze, although ethylene glycol is more common for that application. Adulteration of products with diethylene glycol has led to thousands of deaths worldwide since the first recorded case: the Elixir sulfanilamide incident in 1937. Most of the recalled wines contained up to a few grams of DEG per litre (and many only a fraction of a gram), which meant that dozens of bottles would have to be consumed in a limited period
Ethylene glycol process was commercialized and offered for licenses. Ethylene glycol is primarily used in antifreeze formulations (50%) and as a raw material in the manufacture of polyesters such as polyethylene terephthalate (PET) (40%). The major use of ethylene glycol is as a medium for convective heat transfer in, for example, automobiles and liquid-cooled computers. Ethylene glycol is also commonly used in chilled-water air-conditioning systems that place either the chiller or air handlers outside, or systems that must cool below the freezing temperature of water. In geothermal heating/cooling systems, ethylene glycol is the fluid that transports heat through the use of a
