2,4-Dinitrotoluene

2,4-Dinitrotoluene (2,4-DNT or DNT) is an organic compound with the formula C₇H₆N₂O₄. It is a pale yellow solid that is commonly used as a explosive material.

Chemical Structure

2,4-Dinitrotoluene is composed of a benzene ring substituted with two nitro groups and one methyl group. The nitro groups are located at the 2 and 4 positions of the benzene ring, hence the name 2,4-dinitrotoluene.

Production

2,4-Dinitrotoluene is primarily produced by the nitration of toluene with a mixture of sulfuric acid and nitric acid. The reaction produces a mixture of 2,4-dinitrotoluene and 2,6-dinitrotoluene, which can be separated by distillation.

Uses

2,4-Dinitrotoluene is mainly used in the production of TNT (trinitrotoluene), a common explosive. It is also used as a plasticizer in some plastics and as a dye intermediate.

Health Effects

Exposure to 2,4-dinitrotoluene can cause a variety of health effects. It is a known carcinogen, and can cause anemia, liver damage, and kidney damage. It can also cause skin and eye irritation.

Environmental Impact

2,4-Dinitrotoluene is a persistent organic pollutant, meaning it does not readily degrade in the environment. It can contaminate soil and water, and can bioaccumulate in aquatic organisms.
