1,2,4,5-Tetrachloro-3-nitrobenzene (tecnazene) is an organic compound with the formula HC 6 Cl 4 NO 2. It is a colorless solid. A related isomer is 1,2,3,4-tetrachloro-5-nitrobenzene. It is used as a standard for quantitative analysis by nuclear magnetic resonance. [4] [5]
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. It freezes to give greenish-yellow crystals.
1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to 93% of the product resulting from nitration at the meta-position. The ortho- and para-products occur in only 6% and 1%, respectively.

The compound was first synthesized in 1924 by Oldřich Turek. [3] It can be prepared by the reaction of 1,3,5-trichloro-2,4,6-trinitrobenzene with sodium azide. 1,3,5-trichloro-2,4,6-trinitrobenzene is obtained from the nitration of 1,3,5-trichlorobenzene with nitric acid and sulfuric acid. [3]
Hexanitrobenzene, also known as HNB, is a nitrobenzene compound in which six nitro groups are bonded to all six positions of a central benzene ring. It is a high- density explosive compound with chemical formula C 6 N 6 O 12 , obtained by oxidizing the amine group of pentanitroaniline with hydrogen peroxide in sulfuric acid .

[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 precursor to many derivatives of commercial interest. Hydrogenation gives 1,4-dichloroaniline.
