Abstract: Electrochemical hydrogenation of anthracene was carried out in a divided three-electrode cell with spumous Pb as cathode, Pt as anode and saturated calomel electrode as reference electrode in CH3CN-EtOH-H2O-Bu4NBr electrolytic system.The curve of current-potential was determined and the effects of solvents, water content, supporting electrolyte, anthracene content and temperature were investigated.The optimum conditions were found as potential=-1900 mV, [CH3CN]/[EtOH]=2/1(vol),[H2O]=5.5 mol•L-1,[Bu4NBr]=0.50 mol•L-1 and T=35 ℃.The yield of dihydroanthracene was 91.37% for 6 h electrolysis under these conditions.Based on the result of electrochemical hydrogenation of anthracene,electrochemical hydrogenation of Daqing FCC diesel fuel was studied with spumous Pb as cathode in CH3CN-EtOH-H2O-Bu4NBr system for 5 h electrolysis.Hydrogen content of diesel fuel increased by 1.1%,alkenes were saturated and polycyclic aromatics decreased apparently.
