2,4-Diaminotoluene Use and Manufacturing

Methods of Manufacturing

Nitrification of p-nitrotoluene with mixed acid yields 2, 4-dinitrotoluene, which is then reduced with iron powder to obtain crude product, which is then concentrated and distilled to obtain finished product. Raw material consumption quota: p-nitrotoluene 1600kg/t, sulfuric acid (98%) 1616kg/t, nitric acid (98%) 760kg/t, iron powder (90%) 2700kg/t.

Uses

Aromatic amines likely to have high carcinogenic potency. QSARs of aromatic amines.
