Özet:

 

Cyclic voltammetry (CV) and preparative electrolysis  techniques were used to investigate the reduction of nitrobenzene into  (NB) p-aminophenol (p-Ap).  The electrodes used in CV experiments were  glassy carbon (GC), TiO2/Ti, Sn and Pb.  The preparative  electrolyses were carried out by the use of Pb, Sn, carbon cloth and  TiO2/Ti electrodes.  The CV data were evaluated according to Nicholson-Shain criteria, and  it was deduced that the reductions on TiO2/Ti and GC electrodes  were irreversible and monitored by an  electrochemical-chemical-electrochemical mechanism.  No reduction peak  was observed with Sn and Pb electrodes.  Preparative electrolyses were carried out under current-controlled  conditions in the presence and absence of solvent.  The best yield of  (p-Ap) was obtained with a circulating neat NB electrolysis system on  a TiO2/Ti electrode.
