Abstract :
This Letter reports the first kinetic study of 2-butoxy radicals to employ direct monitoring of the radical. The reactions of 2-butoxy with O2 and NO are investigated using laser-induced fluorescence (LIF). The Arrhenius expressions for the reactions of 2-butoxy with NO (k1) and O2 (k2) in the temperature range 223–311 K have been determined to be k1=(7.50±1.69)×10−12×exp((2.98±0.47) kJ mol−1/RT) cm3 molecule−1 s−1 and k2=(1.33±0.43)×10−15×exp((5.48±0.69) kJ mol−1/RT) cm3 molecule−1 s−1. No pressure dependence was found for the rate constants of the reaction of 2-butoxy with NO at 223 K between 50 and 175 Torr.
