Molecular beam mass spectrometric measurements of mole fraction profiles of reactants, the major products and many intermediate species were performed. The experimental profiles were compared with those calculated using a detailed chemical kinetic mechanism, which was a combination of two detailed mechanisms proposed earlier in the literature for combustion of n-heptane/iso-octane/toluene mixture and for MP oxidation, respectively. Addition of MP was found to reduce mole fractions of many intermediates, which play an important role in formation of PAH, specifically, benzene, cyclopentadienyl, acetylene, propargyl, and vinylacetylene. Analysis of the reaction pathways responsible for formation of naphthalene, a typical representative of small PAH, was performed in order to elucidate the chemical effect of MP addition on its formation.
