Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3, sometimes abbreviated as PhCO 2 Me, where Ph and Me are phenyl and methyl, respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
Benzylamine, also known as phenylmethylamine, is an organic chemical compound with the condensed structural formula C 6 H 5 CH 2 NH 2 (sometimes abbreviated as PhCH 2 NH 2 or BnNH 2).It consists of a benzyl group, C 6 H 5 CH 2, attached to an amine functional group, NH 2.
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-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. It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the acid.
c 6 h 5 no 2 + 3 h 2 → c 6 h 5 nh 2 + 2 h 2 o Aniline is a precursor to urethane polymers, rubber chemicals, pesticides , dyes (particularly azo dyes ), explosives , and pharmaceuticals . Most aniline is consumed in the production of methylenedianiline , a precursor to polyurethanes.
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. [4]
4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene using oxygen or dichromate as oxidants. [7] Alternatively, it has been prepared by nitration of polystyrene followed by oxidation of the alkyl substituent. This method proceeds with improved para/ortho selectivity owing to the steric protection of the ortho positions by the polymer ...
The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical formula C 6 H 4 N 2 O 4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is the most common isomer and it is used in the manufacture of explosives .
