2,4-dinitrochlorobenzene

- Dec 24, 2018-

2,4-dinitrochlorobenzene (referred to as dinitrogen) is a pale yellow or yellowish brown needle-like crystal with bitter almond flavor. It is insoluble in water and slightly soluble in organic solvents such as ether and benzene. It can burn or explode. . Dinitrogen is an important fine chemical intermediate widely used in dyes, pesticides, pharmaceuticals, chemical additives and other fields. In the dye industry, dinitrogen is mainly used in the synthesis of sulfur dyes, disperse dyes and other types of dyes. The main varieties are sulfur black, vulcanized dark blue 3R, vulcanized yellow G, large red base RC, dispersed navy S-2GL, reduced gold RR and Neutral black BL, etc., which are mainly used for the synthesis of sulfur black dyes. In the pesticide industry, dinitrogen can synthesize chloropicrin and dinitrate. In the synthetic chemical intermediate industry, it can be synthesized: 2,4 dinitroaniline, 2,4 dinitrophenol, 2,4 diaminochlorobenzene, 2,4 diaminophenol, 6-chloro (bromo) ) 2,4 dinitroaniline, 2,4 dinitrodiphenyl ether, 2,4 dinitrophenyl ether, 2,4 dinitrobenzene sulfonic acid and 2,4 diaminobenzene Sulfonic acid, etc. In the pharmaceutical industry, benzenesulfonamides can be synthesized.
