Method for inhibiting ethylene oxide polymer growth caused by rust using redox chemistry

摘要

A method for reducing the formation of non-volatile residue (NVR) in alkylene oxide, preferably ethylene oxide, comprising contacting the alkylene oxide with fresh electron source material effective to convert ferric ions to ferrous ions. Iron (Fe0), chromium, and a combination thereof are preferred fresh electron source materials, with iron (Fe0) being most preferred.
