New experimental results have been obtained for the oxidati on of benzen e in a jet-stirred reactor at high temperature (95O-1350 K) at atmospheric pressure and variabl e equivalence ratio (O.3:>0 :>1.5). Molecular species concentration profiles of reactants, stabl e intermediates and final products were obta ined by probe sampling follow ed by on-line and off-line GC analy ses. The oxidation of benzene in these conditions was modeled using a detailed kinetic reaction mechanism (120 species and 921 reactions. most of them reversible) . The proposed mechani sm was also used to simulate the oxidation of benzene at low pressure (0.46 atm) and high pressure in stirred reactor cond itions. The burning velocities of benzene-air mixture s were well-p redicted by the proposed kinetic scheme that was also used to simulate the MBMS results of Bittner and Howard obtained for a fuel-rich benzene-oxygen-arg on premixed flame. The ignition delay s of benzen e-oxygen-argon mixtures measured by Burcat over the range of equivalence ratio s 0.25-2 were modeled . Sensitivity analyses and reaction path analyse s, based on species rates of reaction , were used to interpret the result s. The route s involved in benzene oxidati on have been delineated and are presented in the paper.
