Abstract: PROBLEM TO BE SOLVED: To produce p-nitrobenzoic acid with a single reaction step in high selectivity by heating a styrene-based polymer and nitric acid in the presence of a compound containing a metallic atom. SOLUTION: p-Nitrobenzoic acid is produced by heating (A) a styrene-based polymer and (B) nitric acid in the presence of (C) a compound containing a metallic atom (e.g. manganese dioxide, chromium oxide, iron oxide, cobalt oxide, copper hydroxide or cobalt chloride). The component B may be used in combination with (D) acetic acid. The concentration of the component B is preferably 20-100wt.%, more preferably 30-90wt.%, especially 40-80wt.%. In the case of using the component D, the weight ratio of the component D to the component B is preferably 10-500%, more preferably 20-300%, especially 50-200%.
