The pyrolysis of benzene and toluene – the two primary aromatic molecules, has been studied behind reflectedshock waves using a single pulse shock tube. Experiments were performed at high pressures of 28 and 45 bars and spanning awide temperature range from 1200-1900 K. Stable species sampled from the shock tube were analyzed using standardchromatographic techniques. A detailed chemical kinetic model developed for the oxidation of toluene has been extended topredict the species profiles from the current pyrolysis data set. The model has also been tested against H atom species profilesobtained from toluene and phenyl pyrolysis experiments performed under similar high temperature conditions but at lowerpressures from 1.5-8 bars by Braun-Unkhoff and co-workers at DLR-Stuttgart. The experimental data, the modeldevelopment and its predictions and its implications for simulating chemistry relevant to practical combustion will bediscussed in this work.
