2,4-dinitrochlorobenzene is a chemical compound consisting of a benzene ring with a chloro ( -Cl) and two nitro groups (- NO2) as a substituent. It belongs to the group of Dinitrochlorbenzole in which arise due to different arrangement of the substituents six constitutional isomers.

Production and representation

2,4-dinitrochlorobenzene can be obtained by chlorination of 2,4- Dinitrophenylsulfid.

Properties

2,4-dinitrochlorobenzene is a combustible yellowish solid with a characteristic odor, which is practically insoluble in water. It is present in three forms, wherein only the alpha form is stable. Upon heating, the compound decomposes, chlorine, hydrogen chloride, phosgene, carbon dioxide and carbon monoxide may be produced.

Use

2,4-dinitrochlorobenzene is used as a reagent for alkylation, arylation, and, substitution reactions and the preparation of dyes, photographic chemicals, explosive materials, fungicides, and rubber chemicals.

Safety

2,4-dinitrochlorobenzene may at initial spark, especially including how to detonate explosives. The compound is a very potent contact allergen.
