Hydrogenation of 2,4-Dinitrotoluene to 2,4-Diaminotoluene over Platinum Nanoparticles in a High-Pressure Slurry Reactor

Abstract More stringent requirements for reducing the content of aromatics have brought increasing attention to new catalysts involved in hydrotreating process. The dependence of the 2,4-dinitrotoluene hydrogenation rate on catalyst particle size and kinetic parameters in ethanol–water–diaminotoluene three-component solvent over Pt/C nanoparticle catalyst has been studied. The investigation of the effect of particle size of catalyst on the rate of the reaction corresponds to the zero reaction order. An optimum set of conditions for reaction occurrence is established.
