4-Nitroaniline Some more complicated molecules with other substituents can also be referred to as nitroanilines, for example 4-chloro-3-nitro-aniline. Index of chemical compounds with the same name
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 ...
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 ...
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]
Pigment Yellow 6 (CAS# 2512-29-0), derived from 2-nitrotoluene (diazonium precursor) and aniline (acetoacetanilide precursor) to produce medium yellows. Pigment Yellow 3 (CAS# 6486-23-3), derived from 4-chloro-2-nitroaniline (diazonium precursor) and 2-chloroaniline (acetoacetanilide precursor) to produce greenish-yellows. Pigment Yellow 61 a ...

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 ...
