✦ Synopsis

The slow oxidation of isobutane has been investigated in a static system at 300 °C and 330 °C in the presence of the diluents nitrogen and carbon dioxide. Product analysis by means of gas chromatography shows that the main primary products are ethylene, propylene, isobutene, acetaldehyde, propylene oxide, isobutene oxide, propionaldehyde, isobutyraldehyde, acetone, and t-butanol, with trace amounts of acrolein, methyl oxetane and methacrolein. A mechanism is proposed for the formation and distribution of products based on diffusional studies. The reaction scheme involves a deactivation step whereby vibrationally-excited butylperoxy radicals can undergo deactivation by collision with surrounding gas molecules.
