Ethylene glycol

Production Industrial routes. Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide.Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation: . C 2 H 4 O + H 2 O → HO−CH 2 CH 2 −OH. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures.
