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.
Because of its high boiling point and affinity for water, ethylene glycol is a useful desiccant. Ethylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility.
