Refinement of the rate constans obtained from studies of the H/sub 2/+O/sub 2/ reaction at 500 C has continued. Rate constants for the reactions of H atoms and OH radicals with C/sub 2/-C/sub 5/ 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 H/sub 2/+O/sub 2/ at 480 C. The mechanism of CO/sub 2/ 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 HO/sub 2/ 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 HO/sub 2/ radicals, and preliminary rate constants have been obtained for HO/sub 2/+TMB, and HO/sub 2/+C/sub 2/H/sub 6/ at 440 C. Interpretation of the N/sub 2/O+H/sub 2/ reaction continues.
