| | 4-Nitrobenzoic acid Usage And Synthesis |
| Chemical Properties | light yellow crystalline powder | | Uses | 4-Nitrobenzoic Acid is used in the synthesis of anti-Trypanosoma cruzi agents in the treatment of chagas disease. | | Definition | ChEBI: A nitrobenzoic acid having the nitro group at the 4-position. | | Production Methods | p-Nitrobenzoic acid is produced commercially by the oxidation of 4-nitrotoluene with molecular oxygen. Oxidation with 15 % nitric acid at 175 ℃ produces the acid in 88.5 % yield. An interesting method involves the nitration and subsequent oxidation of polystyrene. This method uses the steric hindrance of the polymer chain to improve the para to ortho ratio of the product. | | Synthesis Reference(s) | Tetrahedron Letters, 26, p. 2387, 1985 DOI: 10.1016/S0040-4039(00)94834-2
Journal of the American Chemical Society, 72, p. 5012, 1950 DOI: 10.1021/ja01167a051 | | General Description | Odorless pale yellow crystals. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | p-Nitrobenzoic acid is incompatible with strong oxidizers. p-Nitrobenzoic acid is also incompatible with strong bases (potassium hydroxide). p-Nitrobenzoic acid may react with cyanides. | | Fire Hazard | p-Nitrobenzoic acid is combustible. | | Toxicology | Among various nitroaromatics, 4-nitrobenzoic acid (4-NBA) is one of the simplest and basic derivates of the explosives. Moreover, 4-NBA harms human health and causes severe water and atmosphere pollution. 4-Nitrobenzoic acid is stable, toxic, and non-biodegradable. US/Zn0 was found to degrade more than 85% of 4-nitrobenzoic acid in 30 min. There was an apparent synergistic effect between ultrasound and Zn[1-2]. | | Purification Methods | Purify it as for 3-nitrobenzoic acid above. The amide has m 201.6o (from H2O).
