ABSTRACT:
A continuous process for the preparation of isomeric mixtures of dinitrotoluene by a single stage nitration of toluene under adiabatic conditions. The reaction enthalpy is used for the removal by distillation of the water of reaction formed during nitration. In this process, toluene is reacted with a nitrating acid having from about 80 to about 100% by weight of an inorganic component having a specified composition and from about 0 to about 20% by weight of an organic component having a specified composition.
