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.
