Ethylene oxide and derivatives
Ethylene oxide (EO), with a demand of over 25 million metric tons annually, is one of the major products from ethylene. As shown in the ethylene oxide value chain diagram to the right, EO can be made from petroleum-based or bio-based ethylene and is used as an intermediate in the manufacture of plastics, fibers, detergents and other downstream chemicals.
More than 70% of EO is consumed in the production of monoethylene glycol (MEG), a key raw material in polyester fibers and PET bottles, and the main ingredient in antifreeze. EO also is used to produce other derivatives including alkoxylates, ethanolamines and glycol ethers.
