A New Look at of the β-pinene–Ozone Reaction Using the Static-Atmospheric Pressure Reactor

β-pinene-ozone reaction without a scavenger was performed for the first time, in the static bag atmospheric pressure reactor coupled into ion trap mass spectrometer. The diffusion coefficients and evolution times (t10-90%) of multiple fragments were used to characterize their neutral parent ions. Main identified products (yields in parentheses) of the reaction such as nopinone (0.58 ± 0.05), formaldehyde (0.19 ± 0.05), HCOOH, CH3COOH, and acetone were successfully associated with their fragment ions. While, 3-hydroxy-nopinone and cis-pinic acid were unsuccessfully associated with their fragments because of the lack of available standard reference mass spectra of these compounds for comparison. Meanwhile, two short-lived intermediates were detected with tentative contributions of products of masses 70 and 97.
