Ethylene glycol (ETHYLENE glycol) is also called "ethylene glycol", "1, 2-ethylenediol", or EG.The formula is (CH2OH)2, which is the simplest diol.Ethylene glycol is a colorless, odorless, sweet-tasting liquid that is toxic to animals and lethal to humans at about 1.6 g/kg. Ethylene glycol can be mutually soluble with water, acetone, but less solubility in ether.Used as solvent, antifreeze and raw material for synthetic polyester.Polyethylene glycol (PEG), a high polymer of ethylene glycol, is a phase transfer catalyst and is also used for cell fusion.Its nitrate is an explosive.
