As can be observed from Fig. 3, the ignition delay times of
2-butanone/O2/Ar mixtures slightly decrease as the pressure increases
from 3 to 6.5 atm. The Serinyel et al. [1] mechanism
slightly over-predicts the ignition delay times for both pressures,
however, the discrepancy is smaller at higher pressure. Serinyel
et al. [1] showed that the ignition delay times of 2-butanone are
sensitive to the decomposition reaction:
