Nitrochlorobenzene is typically synthesized by nitration of chlorobenzene in the presence of sulfuric acid: C 6 H 5 Cl + HNO 3 → O 2 NC 6 H 4 Cl + H 2 O. This reaction affords a mixture of isomers. Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3 ...
For compounds consisting of one benzene ring with only nitro groups and hydrogen as substituents, ... 2-Nitrochlorobenzene; 3-Nitrochlorobenzene; 4-Nitrochlorobenzene;
4-Nitrochlorobenzene is the organic compound with the formula ClC 6 H 4 NO 2. It is a pale yellow solid. 4-Nitrochlorobenzene is a common intermediate in the production of a number of industrially useful compounds, including antioxidants commonly found in rubber. Other isomers with the formula ClC 6 H 4 NO 2 include 2-nitrochlorobenzene and 3 ...
Nitrobenzene is an aromatic nitro compound and the simplest of the nitrobenzenes, with the chemical formula C 6 H 5 NO 2.It is a water-insoluble pale yellow oil with an almond-like odor.
Nitrochlorobenzene may refer to: 2-Nitrochlorobenzene; 3-Nitrochlorobenzene; 4-Nitrochlorobenzene This page was last edited on 31 January ...
2-Nitrochlorobenzene can be reduced to the 2-chloroaniline with Fe/HCl mixture, the Bechamp reduction. [1] 2-Nitrochlorobenzene, like its isomers, is reactive toward nucleophiles, resulting in chloride substitution. With polysulfide, it reacts to give di-orthonitrophenyl disulfide: [2] 2 O 2 NC 6 H 4 Cl + Na 2 S 2 → (O 2 NC 6 H 4 S) 2 + 2 NaCl
DNCB is produced commercially by the nitration of p-nitrochlorobenzene with a mixture of nitric and sulfuric acids. Other methods afford the compound less efficiently include the chlorination of 1,3-dinitrobenzene, nitration of o-nitrochlorobenzene and the dinitration of chlorobenzene. [3]
The following is the reaction mechanism of a nucleophilic aromatic substitution of 2,4-dinitrochlorobenzene (1) in a basic solution in water. Nucleophilic aromatic substitution Since the nitro group is an activator toward nucleophilic substitution, and a meta director, it is able to stabilize the additional electron density (via resonance) when ...
