Integrating the Hydrogenation of Nitrobenzene over Cu/Mgo Catalysts with the 1, 4-Butanediol Dehydrogenation Reaction

Using a fixed bed reactor and Cu/MgO catalysts, the hydrogenation of nitrobenzene to aniline has been combined with the dehydrogenation of 1,4-butanediol to c-butyrolactone reaction in the vapour phase. These Cu/MgO catalysts were made using the co-precipitation method, and they were examined using techniques for BET surface area, XRD, TPR, and N2O pulse-chemisorption. It has been described how the hydrogenation of nitrobenzene over Cu/MgO catalysts coupled with the 1,4-butanediol dehydrogenation reaction has a positive effect.
