Phenol photonitration.
This paper presents some new data on nitrophenol formation from phenol under illumination, and reviews the studies performed on phenol photonitration, from its discovery in 1988 to the very recent elucidation of its reaction pathway by the authors. Recent experimental results account for the pH effect on phenol photonitration. The nitrogen sources so far investigated are nitrate and nitrite, which undergo photolysis upon absorption of near-UV light. These studies have given a relevant information on the role of both nitrate and nitrite as environmental factors. Such processes can take place both in natural waters and in atmospheric hydrometeors.
