Epoxidation method |
abstract |
The present invention provides a method of oxidizing ethylene to form ethylene oxide comprising passing an aqueous stream through a guard bed and one or more ion exchange treatment beds. The guard bed and the aqueous stream contain from about 0.2 to 20% by weight ethylene glycol. The guard bed contains a crosslinked polystyrene resin functionalized with a quaternary ammonium functional moiety and has a surface area greater than 400 m2/g. |
