Cyclohexane oxidation has been studied in a jet-stirred reactor in the temperature range of 750 to 1100 K. at 10 atm. Major and minor species profiles have been obtained by probe sampling and GC analysis. A chemical kinetic reaction mechanism developed from previous studies on smaller hydrocarbons is used to reproduced the experimental data. It has been updated and validated for CI to C5 submechanisms. Good agreement is obtained between computed and measured mole fractions. The major reaction paths of cyclohexane consumption and the formation and the consumption routes of the main products have been identified for our experimental conditions.
