Abstract

PURPOSE: To feed an aqueous solution containing the titled substance and feed the solution to a step before the dehydrating distillation for preparing the titled substance, by separating the aqueous solution discharged from a process for reacting ethylene with oxygen to prepare ethylene oxide by the chromatography with a cation exchange resin.
CONSTITUTION: Ethylene oxide (EO) obtained by catalytically reacting ethylene with oxygen in the vapor phase is reacted with water to give a rection solution containing the titled substance (EG), which is then subjected to the dehydrating distillation to afford EG. In the process, an aqueous solution, containing EG, organic acid components and coloring components, and discharged from the process for preparing EO is concentrated suitably, and separated by the chromatography with a cation exchange resin as a carrier by using water as a developing agent to give an aqueous solution of EG with reduced contents of organic acid components and coloring components, which is then fed to a step before the dehydrating distillation. An aqueous solution of EG obtained by the chromatographic separation is preferably treated further with a cation exchange resin and anion exchange resin.
