WebQuestion. Ethylene oxide is produced by catalytic oxidation of ethylene and air: After the reaction, ethylene oxide is completely separated and the remaining gas flow is recirculated. To prevent nitrogen gas from accumulating, part of the recirculation stream is drained off. The feed consists of pure ethylene and air in the proportions 1:3. WebThese are the complete combustion of ethylene, which is the main source of CO 2, and the further oxidation of ethylene oxide: Industrial processes attain a selectivity of 65-75% ethylene oxide (air process), or 70-80% (O 2 process), with a total heat of reaction of 85-130 kcal(357-546 kJ)/mol ethylene. According to the reaction mechanism, the ...

Ethylene Oxide - an overview ScienceDirect Topics
WebIn the reaction of ethylene with an oxygen-covered catalyst, the absence of an induction period in the pressure-time curve showed that oxidation of ethylene to carbon dioxide and water by a route not through ethylene oxide is possible. The reaction of acetaldehyde with the oxygenated catalyst was too fast to measure.
