Temperature dependence of rate constant for the gas-phase reaction of ozone with linalool

Abstract

To determine the reaction rate coefficient of volatile organic compounds (VOCs) with ozone, the reduction of ozone through a flow-tube reactor was measured by a sensitive chemiluminescent detector. In this study, temperature dependence of the rate constant of ozone with linalool, k(T) = A exp(?B/T), was explored (T = 299-322 K). Consequently, temperature-dependent parameters A and B were experimentally determined as (1.6 ± 0.4) × 10-15 cm3 molecule-1 s-1 and 396 ± 26 K, respectively, for the first time. The rate constant of linalool + O3 reaction varied by 10% with changes in temperatures from 299 to 322 K.
