Abstract: | The feasibility of the electrochemical generation of Fenton's reagent is demonstrated and the subsequent reaction of produced OH radical with benzene studied. Under the proposed working conditions, phenol is obtained as the main product, with current yield as high as 60% (on the basis of 3 F/mole of phenol) and with only traces of other higher oxidized compounds. At fixed H2SO4 concentration and with suitable Fe3+]/O2] ratio, a maximum in current yield is obtained; this yield may presumably be increased if continuous removal of phenol is employed during the electrolysis. |
