Abstract
We studied the transformation of phenol in the presence of nitrous acid in the dark. The main detected intermediates were 2-nitrophenol, 4-nitrophenol and 4-nitrosophenol. For the first time a kinetic analysis of the reaction in a pH interval relevant to environmental chemistry has been carried out. The kinetic data are consistent with phenol transformation being initiated by HNO2. The results are relevant to the chemistry of the atmosphere, where HNO2 forms upon heterogeneous conversion of ·NO2, and to water treatment techniques.
