2,4- Dinitrotoluene is a nitro-substituted in the ortho -and para- position of toluene. The structure consists of a benzene ring with a methyl group (- CH3) and two nitro groups (- NO2) as a substituent. It belongs to the group of dinitrotoluenes, a group of six constitutional isomers.
Representation
2,4-dinitrotoluene is produced as an intermediate in the nitration of o-and p- nitrotoluenes.
It is often weiternitriert to trinitrotoluene ( TNT).
Properties
2,4-dinitrotoluene is yellow, needle- shaped crystals. In a mixture of isomers, it is a brown oil. In water, 2,4-dinitrotoluene is almost insoluble, poorly soluble in acetone and chloroform. It reacts with bases, strong reducing agents and with some metals. 2,4-dinitrotoluene is oxidized with sodium dichromate in sulfuric acid to give 2,4- dinitrobenzoic.
Use
2,4-dinitrotoluene is used as an energetic plasticizer in gunpowder. As the only important of the six dinitrotoluenes 2,4-dinitrotoluene is a raw material for dyes and polyurethane.
Safety
2,4-dinitrotoluene is considered carcinogenic, may teratogenic and mutagenic. It has a large carcinogenic potential. It can be absorbed through skin absorption and leads people to change the blood pigment, which can lead to kidney and liver damage.
