HCID 1140Toluene

Product 1

HCID 74734-Nitrotoluene

Procedure

reacting toluene with nitric acid in a single liquid phase reaction in a first reaction zone at an elevated temperature to provide a single phase mononitrotoluene-containing product mixture, using a reaction mixture that is free of sulfuric acid and that comprises a molar ratio of said nitric acid to said toluene of from 20:1 to 30:1, said reaction being conducted using a combination of fresh and recycled aqueous nitric acid, said combination having a nitric acid concentration not exceeding 75% based upon the weight of nitric acid plus water in said dilute aqueous nitric acid,
