Ethylene glycol is obtained in the process of ethylene oxide hydration and is then purified in the rectification process.
Ethylene glycol is used for manufacturing polyester, which is subsequently used in the production of fibres, films, solid-state resins and other consumables. Additionally, ethylene glycol is used for manufacturing antifreeze fluids.
