Temperature Dependence of Rate Constant for the Gas-phase Reaction of Ozone with Linalool

摘要

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) x 10(-15) cm(3) molecule(-1) s(-1) and 396 +/- 26 K, respectively, for the first time. The rate constant of linalool + O-3 reaction varied by 10% with changes in temperatures from 299 to 322 K.
