The formation of by-products during aqueous ozonation of aniline in the presence of inorganic nitrogen compounds such as ammonium ion, nitrate or nitrite was investigated. During aqueous ozonation of aniline without inorganic nitrogen compounds, the major by-products determined quantitatively were nitrosobenzene, nitrobenzene, o-nitroaniline and m-nitroaniline.By interaction of aniline with nitrite, nitrosobenzene, nitrobenzene, o-nitroaniline and p-nitroaniline were formed. It was recognized that the detectable reaction by-products during aqueous ozonation of aniline in the presence of nitrite were nitrosobenzene, nitrobenzene, o-, m-, p-nitroaniline, 1,2-dinitrobenzene, 1,4-dinitrobenzene and 2,4-dinitroaniline.Especially, p-nitroaniline was formed only by the interaction of aniline with nitrite.This study proposed the possible mechanism of by-products during aqueous ozonation of aniline in the presence of nitrite.
