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)kJmol^-1/RT)cm ³molecule^-1s^-1andk ₂=(1.33±0.43)×10 ^-15×exp((5.48±0.69)kJmol^-1/RT)cm ³molecule^-1s^-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.
