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.
This study shows that minor amount of water plays a very important role in solvent-free hydrogenation of halogenated nitrobenzenes. Forced sponge Pd, the reaction can not 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.
