Ethylene oxide is obtained by direct oxidation of ethylene with oxygen in the presence of a silver catalyst. After extraction, the product is purified in the process of rectification.
Ethylene oxide is used for manufacturing ethylene glycols, polyether polyols, ethanolamines, ethoxylates, and other organic syntheses.
