Abstract
Ignition delays of cyclohexene–oxygen–argon mixtures were measured behind shock. Mixtures contained 1 or 2% of hydrocarbons for equivalence ratios ranging from 0.5 to 2. Reflected shock waves permitted to obtain temperatures from 1050 to 1520 K and pressures from 7.7 to 9.1 atm. The experimental results exhibit an Arrhenius variation vs. temperature.
A detailed mechanism of the combustion of cyclohexene has been written in the line of the mechanism developed previously for the reaction of C~3~C~4~ unsaturated hydrocarbons (propyne, allene, 1,3‐butadiene, butynes); it is based on recent kinetic data values published in the literature and is consistent with thermochemistry. This mechanism has been validated by comparing the results of the simulations to the experimental results obtained for ignition delays. The main reaction pathways have been derived from flow rate and sensitivity analyses for the different temperature areas studied. © 2003 Wiley Periodicals, Inc. Int J Chem Kinet 35: 273–285, 2003
