Reliable kinetic data on isolated elementary combustion reactions spanning a broad temperature range are required for modeling and scaling studies aimed at improving the performance of, and reducing the pollutant formation from, fossil-fuel burning devices. Such data are generally not available. In the present work a new technique, High Temperature Photochemistry (HTP), has been developed to provide such data. It combines the technology of the High-Temperature Fast-Flow Reactors (HTFFR) we developed to study kinetics of metal atom/oxide reactions in the 300 to 1900/sup 0/K range with the flash photolysis technique, which although used widely for study of such combustion reactions, has previously been limited to studies at or near room temperature. This report discusses aspects of a partially complete HTP study on the reaction, OH + C/sub 6/H/sub 6/ ..-->.. C/sub 6/H/sub 5/ + H/sub 2/O in the 600 to 1300/sup 0/K range, and initial work on CH/sub 3/ oxidation by O/sub 2/ and O atoms. The measurements suggest an initial value of k/sub 1/(T) = (4.2 +- 1.5) x 10/sup -11/ exp(-(4.0 +- 0.7) x 10/sup 3//T), cm/sup 3/ molecule/sup -1/ s/sup -1/, in fair agreement with recent results obtained elsewhere in the 500 to 1150/sup 0/K range.
