Kinetics of Hydrogen-Oxygen and Hydrocarbon-Oxygen Reactions
Abstract
(1) Refinement of the rate constants obtained from studies of the H2+O2 reaction at 500 degrees C has continued. (2) 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-tetrameth ylbutane and 2,2,3-trimethylbutane to slowly reacting mixtures of H2+O2 at 480 degrees C. (3) The mechanism of CO2 formation in propionaldehyde oxidation, and of acetone formation in isobutyraldehyde oxidation at 440 degrees C has been examined. Rate constants have been obtained for the initiation process and for attack of HO2 at the various C-H bonds. (4) The homogeneous decomposition of 2,2,3,3-tetramethylbutane in the presence of O2 has provided a source of HO2 radicals and preliminary rate constants for HO2+TMB, and for HO2+C2H6 have been obtained at 440 debrees C. The Thermochemistry of the t-butyl radical, and its reaction with H2 and O2 have been discussed. (5) Interpretation of the N2O+H2 reaction continues. (Author)
