2,4-Dinitrotoluene or Dinitro is an explosive with the formula C6H3(CH3)(NO2)2.
At room temperature 2,4-Dinitrotoluene is a pale yellow to orange crystalline solid.
2,4-Dinitrotoluene is a high explosive and one of the precursors for trinitrotoluene (TNT), which is synthesized through three separate nitrations of toluene.
The first product is mononitrotoluene, 2,4-Dinitrotoluene is the second, and TNT is the third and final product.
Isomers of Dinitrotoluene:
Six positional isomers are possible for dinitrotoluene.
The most common one is 2,4-Dinitrotoluene.
The nitration of toluene gives sequentially mononitrotoluene, DNT, and finally TNT.
2,4-Dinitrotoluene is the principal product from dinitration, the other main product being about 30% 1,3-DN2-T.
The nitration of 4-nitrotoluene gives 2,4-Dinitrotoluene.
Applications:
Most 2,4-Dinitrotoluene is used in the production of toluene diisocyanate, which is used to produce flexible polyurethane foams.
2,4-Dinitrotoluene is hydrogenated to produce 2,4-toluenediamine, which in turn is phosgenated to give toluene diisocyanate.
In this way, about 1.4 billion kilograms are produced annually, as of the years 1999–2000.
Other uses include the explosives industry.
2,4-Dinitrotoluene is not used by itself as an explosive, but some of the production is converted to TNT.
2,4-Dinitrotoluene is frequently used as a plasticizer, deterrent coating, and burn rate modifier in propellants (e.g., smokeless gunpowders).
In this application 2,4-Dinitrotoluene is often used together with dibutyl phthalate.
At room temperature 2,4-Dinitrotoluene is a pale yellow to orange crystalline solid.
