In our previous work (D. Darcy, C.J. Tobin, K. Yasunaga, J.M. Simmie, J. Wurmel, W.K. Metcalfe, T. Niass, S.S. Ahmed, C.K. Westbrook, H.J. Curran, Combust. Flame 159 (2012) 2219-2232), ignition delay times of n-butylbenzene in air were measured using a shock tube over a temperature range of 980-1360 K, at reflected shock pressures of 1, 10, and 30 atm, and at equivalence ratios of 0.3, 0.5, 1.0 and 2.0. In the present study, these measurements have been extended to 50 atm and to lower temperatures using a rapid compression machine in the temperature range 730-1020 K, at compressed gas pressures of 10, 30 and 50 atm, over the same equivalence ratio range. Trends in ignition delay times over the wide temperature range were identified. The chemical kinetic model for n-butylbenzene, which was validated for the original shock tube data, was extended by adding low-temperature kinetics. The updated chemical kinetic model captures the general trend in reactivity of n-butylbenzene over the w...
