Abstract
ABSTRACTThe 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): 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.
