Infrared Fourier transform spectroscopic studies suggest that the molecules of 4-nitrobenzoic acid gets adsorbed on the surfaces of fine silver powder as carboxylate. Application 4-Nitrobenzoic acid is produced commercially by the oxidation of 4-nitrotoluene with molecular oxygen. Oxidation with 15% nitric acid at 175 °C produces the acid in 88.5% yield. /Another/ method involves the nitration and subsequent oxidation of polystyrene. 4-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is a pale yellow solid. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anesthetic procaine and folic acid.

Explanation: I. The Nitration Mechanism. (a) Formation of nitronium ion. (i) The sulfuric acid protonates the nitric acid. The acidity increase of ortho-nitrobenzoic acid compared with para-nitrobenzoic acid is believed to be a result of the so called "ortho effect". The explanation is  a) Para nitro benzoic acid is more acidic than benzoic acid because of the NO2 functional group which is a electron withdrawing group . 4-nitrobenzoic acid - cas 62-23-7, synthesis, structure, density, melting point, boiling point.
