| Abstract: | Kinetic studies of the nitroxidation of isobutene by NO show that the reaction follows a  redox mechanism in the temperature range of 300–400°C. This mechanism implies an interaction between dehydrogenated isobutene  -allyl radical and atomic nitrogen due to the decomposition of NO by the reduced catalyst, which is then reoxidized.
