摘要
Electrochemical hydrogenation of anthracene was carr ie d out in a divided three-electrode cell with spumous Pb as cathode, Pt as anode and saturated calomel electrode as reference electrode in CH 3CN-EtOH-H 2O -Bu 4NBr electrolytic system.The curve of current-potential was determined an d the effects of solvents, water content, supporting electrolyte, anthracene con tent and temperature were investigated.The optimum conditions were found as pote ntial=-1900 mV, [CH 3CN]/[EtOH]=2/1(vol),[H 2O]=5.5 mol·L -1, [Bu 4NBr]=0.50 mol·L -1 and T=35 ℃.The yield of dihydroanthracen e was 91.37% for 6 h electrolysis under these conditions.Based on the result of electrochemical hydrogenation of anthracene,electrochemical hydrogenation of Da qing FCC diesel fuel was studied with spumous Pb as cathode in CH 3CN-EtOH-H 2O-Bu 4NBr system for 5 h electrolysis.Hydrogen content of diesel fuel incre ased by 1.1%,alkenes were saturated and polycyclic aromatics decreased apparent ly.
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-Bu4 NBr 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°C. 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.
