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.
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 Â°C, or when its boiling point has to be raised.
