A study of the electrochemical reduction of nitrobenzene to p-aminophenol in a packed bed electrode reactor

Electrochemical reduction of nitrobenzene and 4-nitrophenol in the room temperature ionic liquid [C4dmim][N(Tf)2]

“…A typical reaction scheme showing the formation of these products in aprotic solvents is given in Scheme 1. In protic media, the predominant reduction product is either paminophenol (HOPhNH 2 ) [26,27] or aniline (PhNH 2 ) [28] (depending upon the strength of the acid medium) via the intermediate N-phenylhydroxylamine.…”

Electrocatalytic properties of Cu–Zr amorphous alloy towards the electrochemical hydrogenation of nitrobenzene

“…Several such electrosyntheses have been considered for commercial exploitation and *Corresponding author. Department of Chemistry, Imperial College of have been the subject of pilot scale studies [19,20]. The…”

“…Because no substantial change in the morpholoelectrodes in aqueous solutions have suggested that the gy of electrode CuZr-1 is observed in Fig. 6a, the increase electrochemical reduction of nitrobenzene is a totally in the peak current by a factor of 2 must be caused by the irreversible reaction under diffusion control [20,22,37,38].…”

Highly efficient electrochemical and chemical hydrogenation of 4-nitrophenol using recyclable narrow mesoporous magnetic CoPt nanowires

“…However, the electrochemical reduction of nitro-aromatic compounds is complicated as a consequence of the various chemical transformations involved in the process, which are strongly dependent on pH, solvent and catalytic nature. [42][43][44][45] Nonetheless, in protic media, the predominant reduction product is either aminophenol and/or aniline, depending upon the strength of the acidic medium, [46][47][48] while in aprotic media it is 4-hydroxylaminophenol. For example, in an acidic electrolyte (10% H 2 SO 4 ), nitrophenol is reduced to aminophenol in a virtually quantitative yield.…”
