ABSTRACT:
Sulphuric and nitric acids present in dinitrotoluene are separated from the dinitrotoluene by adding up to 10 wt. % water (based on quantity of dinitrotoluene) to the mixture of dinitrotoluene, sulphuric acid and nitric acid, mixing and separating the aqueous phase containing nitric and sulphuric acids. The mixtures treated by this process generally contain up to 5 wt. % nitric acid and up to 6 wt. % sulphuric acid.
