Reactions of oxygenated radicals in the gas phase. Part 14. Reactions of t-butylperoxyl radicals

Abstract

The photo-oxidation of trans-2,2′-azoisobutane has been studied between 313 and 393 K. The principal products are acetone, t-butyl alcohol, t-butyl hydroperoxide, and formaldehyde. The yields of hydroperoxide and formaldehyde come to a limiting value during photolysis. Detailed analyses of products were carried out at different temperatures and total pressures. Further experiments were performed in which t-butyl hydroperoxide was added. The reaction was simulated over this wide range of conditions. The importance of reactions between the various alkylperoxyl radicals is emphasised.
