The three isomers of nitrobenzoic acid are: 2-Nitrobenzoic acid is prepared by oxidation of 2-nitrotoluene. 3-Nitrobenzoic acid is a precursor to 3-aminobenzoic acid, which in turn is used to prepare some dyes. It can be prepared by nitration of benzoic acid.
3-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is an aromatic compound and under standard conditions, it is an off-white solid. The two substituents are in a meta position with respect to each other, giving the alternative name of m-nitrobenzoic acid.
2-Nitrobenzoic acid or o-nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is prepared by oxidation of 2-nitrotoluene with nitric acid. [1] In consists of a carboxylic acid group and a nitro group in the ortho configuration. Reduction of the nitro group into an amine produces anthranilic acid.
A few types of aromatic compounds, such as phenol, will react without a catalyst, but for typical benzene derivatives with less reactive substrates, a Lewis acid is required as a catalyst. Typical Lewis acid catalysts include AlCl 3, FeCl 3, FeBr 3 and ZnCl 2. These work by forming a highly electrophilic complex which is attacked by the benzene ...
Nitration of 3-Methylbenzoic acid. Similar results were also observed on the nitration of 3-methylbenzoic acid in which 5-methyl-2-nitrobenzoic acid and 3-methyl-2-nitrobenzoic acid were obtained as the major compounds, whereas 3-methyl-4-nitrobenzoic acid was reported as a minor compound. [5]
3,5-dinitrobenzoic acid-2-propylester (mp.: 123 °C [4]). Compared to 4-nitrobenzoic acid, another acid that is used similarly, derivates of 3,5-dinitrobenzoic acid have higher melting points, so that it is preferred when the 4-nitrobenzoic acid derivate has a melting point too low to be accurately identified.

These are chemical active centers for acid-catalyzed transalkylation reaction. Zeolites of varying sizes are used to perform transalkylation on different substrates. For example, zeolites with a pore size of 5.5Å are suitable for benzene, toluene, xylenes and trimethylbenzenes transalkylations. [5] [3] [6]
