Abstract

The gas phase reactions of the ozonolysis of three monoterpene alcohols: linalool, nerol, and citronellol, were investigated using a rigid atmospheric simulation chamber coupled to a proton transfer reaction-mass spectrometer (PTR-ToF-MS) to monitor the concentrations of the investigated compounds. Reaction rate constants were determined over the temperature range of 298–353 K at atmospheric pressure. Reaction rate constants (×10¹⁶ cm³ molecule⁻¹ s⁻¹) at 298 K are 3.12 ± 0.30 for linalool, 8.89 ± 0.90 for nerol, and 2.11 ± 0.10 for citronellol. The following Arrhenius expressions were established (cm³ molecule⁻¹ s⁻¹): $\begin{matrix} k_{linalool + O_{3}} = (3.52 \pm 1.80) \times 10^{- 13} \exp (- (2115 \pm 163) / T) \\ k_{nerol + O_{3}} = (1.74 \pm 1.50) \times 10^{- 12} \exp (- (2260 \pm 268) / T) \\ k_{citronellol + O_{3}} = (1.63 \pm 1.00) \times 10^{- 13} \exp (- (1968 \pm 190) / T) \end{matrix}$

The obtained rate constants are presented and compared to those found in the literature at room temperature, as well as to homologous alkenes. Based on the obtained rate constants, the tropospheric lifetimes of the studied compounds due to their elimination by ozonolysis were estimated to be about 1 hour.

期刊介绍： As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
