ethylene glycol. (glÄ«'kÃ´l') A poisonous, syrupy, colorless alcohol used as an antifreeze in heating and cooling systems that use water. Ethylene glycol is chemically like ethanol but has two hydroxyl (OH) groups instead of one. Also called glycol. Chemical formula: C2H6O2.
Ethylene oxide is also hydrolyzed to produce ethylene glycol, widely used as an automotive antifreeze as well as higher molecular weight glycols, glycol ethers and polyethylene terephthalate. Ethylene undergoes oxidation by palladium to give acetaldehyde. This conversion remains a major industrial process (10M kg/y).
