Procedure

U.S. Pat. No. 6,005,143 discloses a process for the adiabatic hydrogenation of dinitrotoluene in a monolith catalyst employing nickel and palladium as the catalytic metals. A single phase dinitrotoluene/water mixture in the absence of solvent is cycled through the monolith catalyst under plug flow conditions for producing toluenediamine.
