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-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. [5]

A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...
2,5-Diaminotoluene is prepared through electrolytic reduction of 2,5-dinitrotoluene. [3] Other methods include the reductive cleavage of 4-amino-2,3'-dimethylazobenzene as well as the condensation of 2-amino-1-methylbenzene and toluene-4-sulphonyl chloride to produce 4-toluenesulphono-2-toluidide which is then coupled with diazotized aminobenzenesulphonic acid and reduced.
