Ethylene glycol Wikipedia

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: C2H4O + H2O → HO−CH2CH2−OHThis reaction can be catalyzed by either acids or bases, or can occur at neutral pHunder elevated temperatures. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of
