A green chemical approach for nitration of aromatic compounds
Abstract
Photochemical aromatic nitration of phenol and salicylic acid has been carried out in the presence of UV radiations and formation of products has been observed spectrophotometrically. The effect of various operating variables like pH, concentration of nitrite ion, formate ion, phenol and salicylic acid, etc. on the rate of the reaction has also been observed. A tentative mechanism involving NO2· radicals has been proposed for photochemical nitration of phenol and salicylic acid.
