Molecular Formula: C₂H₆O₂

Produced by a non-catalytic hydration of ethylene oxide and water at an elevated temperature, Ethylene Glycol is an organic compound; widely used as an automotive anti-freeze and also used in the industry for the manufacture of polyester fibre and films. It was initially produced as a substitute for glycerol which was used in the manufacturing of explosives. In appearance it is a colourless and an odourless liquid which is hygroscopic in nature and hence completely miscible with many other liquids. It has a relatively shorter lifespan after being exposed because it breaks down easily after being used for any application in an open environment in about 10 days to a couple of weeks. Ethylene glycol when produced is often purified in purification columns to separate mono, di and triethylene glycols, meeting the product specifications.

Applications:

87% of Ethylene Glycol produced today is used to make Polyethylene Terephthalate melt which as of 2010 has a global consumption of approximately 54 million tons. It has also been used in the manufacture of unsaturated polyester resins, textile softeners, plasticisers etc.

Its second most important use is as a coolant and a heat transfer agent where it has successfully been used in automotive antifreeze and coolants and more importantly in cooling systems, from standard cooling systems to large geothermal systems as a liquid used to transport heat with the help of heat pumps.

Minor uses of ethylene glycol include the manufacture of capacitors, as a chemical intermediate in the manufacture of 1,4-dioxane, and as an additive to prevent corrosion in liquid cooling systems for personal computers.

Ethylene Glycol has also been used as a solvent coupler as a stabilizer against gel formation.
