Improved process for preparing dinitrotoluene by reacting toluene with concentrated nitric acid. The process reacts toluene with a large excess of concentrated nitric acid, in the presence of a select hydrated nitrate salt which is effective in minimizing explosive hazards, to produce a product which has substantially reduced by-product content.

A process for the production of dinitrotoluene which comprises reacting, in the liquid phase, toluene with concentrated nitric acid, using at least 10 moles of nitric acid per mole of toluene, the reaction being carried out in the presence of a hydrated nitrate salt in an effective amount to reduce the hazard of detonation, the relative proportions of reactants and salt being such as to provide, upon completion of the reaction, a product mixture containing less than 15 percent by weight of dinitrotoluene.
