Uses and applications

What the substance is used for, by industry and function

Intermediates for the production of toluene diisocyanate and dyestuffs, also used as explosives. (Dinitrotoluenes).

In the manufacture of explosives.

Industrial uses: Intermediate.

Roles

  • explosive

How it is made

Dinitration of toluene results in the formation of a number of isomeric products, and with a typical sulfuric-nitric acid nitrating mixture the following mixture of isomers is obtained: 75 wt% 2,4-dinitrotoluene, 19 wt% 2,6-dinitrotoluene, 2.5 wt% 3,4-dinitrotoluene, 1 wt% 2,3-dinitrotoluene, and 0.5 wt% 2,5-dinitrotoluene.

2,3-DNT and 3,4-DNT, are derived from nitration of m-nitrotoluene.
