4-Nitroaniline is produced industrially via the amination of 4-nitrochlorobenzene: [3] ClC 6 H 4 NO 2 + 2 NH 3 → H 2 NC 6 H 4 NO 2 + NH 4 Cl. Below is a laboratory synthesis of 4-nitroaniline from aniline. The key step in this reaction sequence is an electrophilic aromatic substitution to install the nitro group para to the amino group. The ...
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 ...
The term nitroaniline in chemistry refers to a derivative of aniline (C 6 H 5 NH 2) containing a nitro group (—NO 2) There are three simple nitroanilines of formula C 6 H 4 (NH 2)(NO 2) which differ only in the position of the nitro group: 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline
2,6-Dichloro-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 2 Cl 2 NH 2. It is the most widely discussed isomer of dichloronitroaniline, mainly as a precursor to the azo dye disperse brown 1. It is prepared by treatment of 4-nitroaniline with a mixture of hydrochloric acid and hydrogen peroxide (a source of chlorine). [3] [4]
Disperse Yellow 42, a popular dye for polyesters, is derived from 1,4-dichloro-2-nitrobenzene. [1] 1,4-Dichloro-2-nitrobenzene is an organic compound with the formula C 6 H 3 Cl 2 NO 2. One of several isomers of dichloronitrobenzene, it is a yellow solid that is insoluble in water. It is produced by nitration of 1,4-dichlorobenzene. It is a ...
Dichloroanilines are chemical compounds which consist of an aniline ring substituted with two chlorine atoms and have the molecular formula C 6 H 5 Cl 2 N. There are six isomers, varying in the positions of the chlorine atoms around the ring relative to the amino group. As aniline derivatives, they are named with the amino group in position 1.
2-Nitroaniline is prepared commercially by the reaction of 2-nitrochlorobenzene with ammonia: [2] ClC 6 H 4 NO 2 + 2 NH 3 → H 2 NC 6 H 4 NO 2 + NH 4 Cl. Many other methods exist for the synthesis of this compound. Direct nitration of aniline is inefficient since anilinium is produced instead. Nitration of acetanilide gives only traces of 2 ...
4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin, anilofos, monolinuron, and chlorphthalim.
