Abstract

PURPOSE: To recover ethylene glycol in high yield, by subjecting an agueous solution containing the ethylene glycol discharged in the process of oxidizing ethylene with oxygen to obtain ethylene oxide to the column chromatography, and separating the impurities from the aqueous solution.
CONSTITUTION: A reaction gas obtained by catalytically oxidizing ethylene with oxygen in the vapor phase, and containing ethylene oxide is washed with water to give the ethylene oxide. In the process, a discharged agueous solution containing ethylene glycol (EG) and organic acid components and coloring components is, if desired, suitably concentrated, subjected to the column chromatography with a cation exchange resin as a carrier by using water as a developing agent and separated into at least three parts, i.e. the first part containing organic acid components, coloring components and almost no EG, the second part containing organic acid components, coloring components and EG in a low concentration and the third component containing EG in a high concentration. The second part is then circulated through the preparing process of the ethylene oxide or the chromatographic separation step to recover the third part as an aqueous solution of EG.
