| Abstract: | Latest advances in preparation of ethylene glycol (EG) were reviewed, including preparation of EG via catalytic hydration from ethylene oxide (EO) andethylene carbonate (EC), as well as via syngas. Anion exchange resin, quaternary phosphonium halides and Nb2O5/α-Al2O3 had been used as catalysts to synthesis EG from EO. Lower energy consumption, higher EG selectivity and yield were obtained. Synthesis gas-based routes were also introduced in this paper. All methodswere compared and suggestions for the future development were pointed out. |
