In this work the gas-phase reactions of ozone with aromatic hydrocarbons (toluene, m-xylene, ethylbenzene) were studied. The reactions were carried out in the flow system. Ozone was formed by the ultraviolet radiation emitted by a mercury lamp, in order to simulate the atmospheric conditions. The changes with time in the concentration of ozone, hydrocarbons and formed products were investigated. Qualitative and quantitative analyses were done by means of the gas chromatography and colorimetry. The reaction rate constants were calculated. Based on the obtained results, a reactivity of tested pollutions in contact with ozone were explained.
