Description:
The chemical composition of secondary organic aerosol formed in an
environmental chamber from ozonolysis of 1-tetradecene in humid and dry air was
determined using a thermal desorption particle beam mass spectrometer (TDPBMS).
The major products are src="/ncer/pubs/images/alpha.gif">-hydroxytridecyl hydroperoxide and bis(
border=0 src="/ncer/pubs/images/alpha.gif">-hydroxytridecyl) peroxide in humid
air and symmetric C26 and asymmetric C14 secondary ozonides in dry air. The
hydroperoxide is formed by reaction of stabilized Criegee biradicals with water
vapor, and the peroxide (a peroxyhemiacetal) is formed by subsequent reaction of
the hydroperoxide with tridecanal. The secondary ozonides are formed by
reactions of stabilized Criegee biradicals with tridecanal and formaldehyde.
Tridecanoic acid was also observed in both experiments. These compounds have
very low vapor pressures and are stable on the 3-h time scale of the
environmental chamber experiments. When collected aerosol was analyzed by gas
chromatography, the hydroperoxides, peroxides, and secondary ozonides thermally
decomposed to more volatile compounds, including tridecanal, tridecanoic acid,
and a few unidentified products.
