pH Control in Ethylene Oxide Production

Ethylene oxide is a large volume intermediate chemical. It is used as a precursor in the manufacture of different chemicals varying from ethylene glycol, which is used in automotive antifreeze, to the production of polyester.

Preventing complete oxidation of ethylene to water and CO2 has long been one of the biggest hurdles in maximizing EO output. Thanks to developments in catalyst technology, these problems have been sig­nificantly reduced.
