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 ...
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
2-Nitrochlorobenzene is an organic compound with the formula ClC 6 H 4 NO 2. It is one of three isomeric nitrochlorobenzenes . [ 1 ] It is a yellow crystalline solid that is important as a precursor to other compounds due to its two functional groups.
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-nitrochlorobenzene. Since the above synthetic route does not efficiently produce the 3-isomer, the route most commonly used by chemists is the chlorination of nitrobenzene .
These mononitrochlorobenzenes are converted to related 2-nitrophenol, 2-nitroanisole, bis(2-nitrophenyl)disulfide, and 2-nitroaniline by nucleophilic displacement of the chloride, with respectively sodium hydroxide, sodium methoxide, sodium disulfide, and ammonia. The conversions of the 4-nitro derivative are similar. [9]
A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...

2,4-Dinitrochlorobenzene (DNCB) is an organic compound with the chemical formula (O 2 N) 2 C 6 H 3 Cl. It is a yellow solid that is soluble in organic solvents. It is an important intermediate for the industrial production of other compounds. [2] DNCB is produced commercially by the nitration of p-nitrochlorobenzene with a mixture of nitric and ...
