Kinetics of hydrogen-oxygen and hydrocarbon-oxygen reactions. Final report 1 Oct 72--31 Mar 77
There has been a continuing refinement in the interpretation of the second limit (using mixtures with very low concentrations of O/sub 2/) and slow reaction (making allowance for self-heating) of H/sub 2/ + O/sub 2/ mixtures at 500/sup 0/C. Studies of CO + H/sub 2/ + O/sub 2/ mixtures have given rate constants for reactions of CO with radicals. Studies of the addition of alkanes and related compounds to slowly reacting mixtures of H/sub 2/ + O/sub 2/ have continued. The mechanism for the formation of conjugate alkene has been elucidated, and the rate constants of a large number of elementary reactions have been determined. Studies have been made of the oxidation of HCHO, CH/sub 3/CHO, C/sub 2/H/sub 5/CHO, n- and i-C/sub 3/H/sub 7/CHO, and the rate constants evaluated for a number of the elementary steps involved. The homogeneous decomposition of hexamethylethane has been studied over the temperature range 440-540 C as a potential source both of t-butyl radicals and of HO/sub 2/ radicals. A detailed study and interpretation has been made of the reaction between H/sub 2/ N/sub 2/O at temperatures of 500/sup 0/C and 600/sup 0/C. Rate constants for some of the elementary steps have been obtained. (Author)
