Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...
