This pale yellow crystalline solid is well known as a precursor to trinitrotoluene (TNT) but is mainly produced as a precursor to toluene diisocyanate. Isomers of dinitrotoluene The most common of the six positional isomers possible for dinitrotoluene is 2,4-dinitrotoluene. The nitration of toluene gives sequentially mononitrotoluene, DNT, and finally TNT. 2,4-DNT 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-DNT.Gerald Booth Nitro Compounds, Aromatic Ullmann's Encyclopedia of Industrial Chemistry 2007 Wiley-VCH Weinheim 10.1002/14356007.a17_411 978-3527306732 Applications Most DNT is used in the production of toluene diisocyanate, which is used to produce flexible polyurethane foams. DNT 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. Six, C. Richter, F. Isocyanates, Organic 10.1002/14356007.a14_611 Other uses include the explosives industry. It is not used by itself as an explosive, but some of the production is converted to TNT. Dinitrotoluene is frequently used as a plasticizer, deterrent coating, and burn rate modifier in propellants (e.g., smokeless gunpowders). As it is carcinogenic and toxic, modern formulations tend to avoid its use. In this application it is often used together with dibutyl phthalate.November 2009 Toxicity Dinitrotoluenes are highly toxic with a threshold limit value (TLV) of 1.5 mg/m3.NIOSH Pocket Guide to Chemical Hazards - Dinitroluene It converts hemoglobin into methemoglobin. 2,4-Dinitrotoluene is also a listed hazardous waste under 40 CFR 261.24. Its United States Environmental Protection Agency (EPA) Hazardous Waste Number is D030. The maximum concentration that may be contained to not have toxic characteristics is 0.13 mg/L.
