Process for preparing toluenediamines by catalytic hydrogenation

Process for preparing toluenediamines by catalytic hydrogenation

Toluenediamine preparation comprises reacting dinitrotoluene with hydrogen in presence of catalyst. The dinitrotoluene contains carbon dioxide in physically dissolved or chemically bonded form (less than 0.175 mol.% based on molar dinitrotoluene).
