Smog chamber experiments were performed to investigate the composition of products formed from photooxidation of aromatic
hydrocarbon ethylbenzene. Vacuum ultraviolet photoionization mass spectrometer and aerosol time-of-flight mass spectrometer were
used to measure the products in the gas and particle phases in real-time. Experimental results demonstrated that ethylphenol,
methylglyoxal, phenol, benzaldehyde, and 2-ethylfurane were the predominant photooxidation products in both the gas and particle
phases. However, there were some di erences between detected gas phase products and those of particle phase, for example,
2-ethylfurane, ethylglyoxylic acid, nitroethylbenzene, 3,4-dioxopentanal and ethyl-nitrophenol were only existing in the particle-phase.
The possible reaction mechanisms leading to these products were also discussed and proposed.
