Experimental results are presented from plug flow reactor studies of the lean oxidation of iso-octane and compared to modeling results using a detailed kinetic mechanism. Two sets of experiments performed at 9 atm are presented: a temperature sweep from low temperature through the NTC region and temporal species profiles for an initial temperature within the low temperature regime. Species observed include C8 conjugate olefins, C8 cyclic ethers, acetone, acetaldehyde, iso-butyraldehyde, 2,2-dimethyl-propanal, iso-butene, propene, C7 olefins, and iso-butene oxide. In general the model predicts the overall trends observed in the experimental results, including the temperatures at which the NTC region begins and ends. However, it significantly over-predicts the extent of reaction in the low temperature regime.
