Abstract

The synthesis of ethylene glycol (EG) from ethylene oxide (EO) by catalytic hydration was investigated. Using glycerol as solvent to recycle catalyst could raise the selectivity of EG; the major factor was solvent dosage. Selectivity of EG could reach 95.63-97.92% when NY was used as catalyst, glycerol as solvent, n(H₂O)/n(EO) 1-4, mass fraction of EG < 30%, and mass fraction of catalyst > 7.2%. The results are important in reducing energy consumption of the process.
