The rate constant for the overall reaction
OH +
1-butanol → products was determined in the temperature range 900 to 1200 K from measurements of
OH concentration time histories in reflected
shock wave experiments of
tert-butyl hydroperoxide (TBHP) as a fast source of
OH radicals with
1-butanol in excess. Narrow-linewidth
laser absorption was employed for the quantitative
OH concentration measurement. A detailed kinetic mechanism was constructed that includes updated rate constants for
1-butanol and TBHP kinetics that influence the near-first-order
OH concentration decay under the present experimental conditions, and this mechanism was used to facilitate the rate constant determination. The current work improves upon previous experimental studies of the title rate constant by utilizing a rigorously generated kinetic model to describe secondary reactions. Additionally, the current work extends the temperature range of experimental data in the literature for the title reaction under combustion-relevant conditions, presenting the first measurements from 900 to 1000 K. Over the entire temperature range studied, the overall rate constant can be expressed in Arrhenius form as 3.24 × 10(-10) exp(-2505/T [K]) cm(3) molecule(-1) s(-1). The influence of secondary reactions on the overall
OH decay rate is discussed, and a detailed uncertainty analysis is performed yielding an overall uncertainty in the measured rate constant of ±20% at 1197 K and ±23% at 925 K. The results are compared with previous experimental and theoretical studies on the rate constant for the title reaction and reasonable agreement is found when the earlier experimental data were reinterpreted.
