Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available. Diethylene glycol is one of several glycols derived from ethylene oxide. PAN is soluble in polar solvents, such as dimethylformamide, dimethylacetamide, ethylene and propylene carbonates. Ethanol may be administered as an antidote to methanol, isopropyl alcohol and ethylene glycol poisoning. Bulk polymers derived from ethylene and propylene are often prepared via Ziegler-Natta catalysis. Natural gas is dehydrated by ethylene glycol. These two gases aer converted to ethylene and propylene. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. Copolymers are formed with ethylene or styrene. Polymerization of ethylene oxide is an exothermic process. In 1859, Wurtz prepared ethylene glycol via the hydration of ethylene oxide. Yttrium compounds are used as a catalyst for ethylene polymerization. Signs of ethylene glycol poisoning depend upon the time after ingestion. This antidotal treatment forms the mainstay of management of ethylene glycol poisoning.
