The promoting role of minor amount of water in solvent-free hydrogenation of halogenated nitrobenzenes
2014
Abstract This study shows that minor amount of water plays a very important role in solvent-free hydrogenation of halogenated nitrobenzenes. For dried sponge Pd, the reaction cannot occur in the absence of water. For Pd/C catalyst, minor amount of water reduces the induction time, increases the reaction rate and reaction TOFs. Water might enhance the diffusion, adsorption and dissociation of H 2 on Pd catalysts.
