Kinetics of Hydrogen-Oxygen and Hydrocarbon-Oxygen Reactions.
Abstract
Refinement of the rate constans obtained from studies of the H2+O2 reaction at 500 C has continued. Rate constants for the reactions of H atoms and OH radicals with C2-C5 alkanes have been refined, and Arrhenius parameters obtained. New studies have been made of the addition of 2,2,3,3-tetramethylbutane and 2,2,3-trimethylbutane to slowly reacting mixtures of H2+O2 at 480 C. The mechanism of CO2 formation in propionaldehyde oxidation, and of acetone formation in isobutyraldehyde oxidation at 440 C has been examined. Rate constants have been obtained for the initiation process and for attack of HO2 at the various C-H bonds. The homogeneous decomposition of 2,2,3,3-tetramethylbutane (TMB) in the presence of O2 has been shown to be an excellent source of HO2 radicals, and preliminary rate constants have been obtained for HO2+TMB, and HO2+C2H6 at 440 C. Interpretation of the N2O+H2 reaction continues. (Author)
