It can be prepared by nitration of benzoic acid. It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the acid. 4-Nitrobenzoic acid is a precursor to 4-aminobenzoic acid, which is in turn used to prepare the anesthetic procaine. 4-Nitrobenzoic acid is prepared by ...

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

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.
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.
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.

2-Nitrophenylacetic acid is an organic compound used in organic synthesis that has also been used as an herbicide. It is a derivative of phenylacetic acid , containing a phenyl functional group , a carboxylic acid functional group, and a nitro functional group.
