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 ...
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-Methoxy-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 3 (OCH 3)NH 2. [2] It is one of four isomers of methoxynitroaniline. The compound is a precursor to the commercial Pigment Yellow 74 .
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 ...
3-Nitroaniline is an organic compound with the formula H 2 NC 6 H 4 NO 2. A yellow solid, it is a derivative of aniline , carrying a nitro functional group in position 3. It is an isomer of 2-nitroaniline and 4-nitroaniline .
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4] C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5] C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2 H 2 O
