OH-Initiated Oxidation of P-Xylene Under Atmospheric Conditions

The OH-initiated oxidation of p-xylene has been studied under simulated atmospheric conditions in a 420 1 reaction chamber using in situ long-path FT-IR absorption spectroscopy to determine product distributions. NOx/p-xylene/hγ /air and HO2NO2/NO were used as photolytic and ‘dark’ hydroxyl radical sources, respectively.
