Ignition delay times of mixtures of n-C₄H₁₀ and i-C₄H₁₀ (1.0% C₄H₁₀ and = 0.72 diluted in Ar) havebeen measured behind reflected shock waves by monitoring time histories of UV emission and pressure in thetemperature range 1200-1600 K. The ignition delay time of i-C₄H₁₀ was longer than that of n-C₄H₁₀. It isalso found that the ignition delay time of i-C₄H₁₀ decreased with the addition of n-C₄H₁₀. A detailed chemicalkinetic mechanism for the high temperature oxidation of mixtures of n-C₄H₁₀ and i-C₄H₁₀ has been constructed.Rate constants for important reactions used in the model were selected from reliable literature values and werenot adjusted as parameters. The model can reproduce measured ignition delay times by less than 25% accuracy,and the temperature dependence of simulated ignition delay times is in good agreement with experimentaldata. The difference in combustion characteristics between butane isomers is discussed on the basis of thechemical kinetic mechanism.
