| Abstract: | A novel ionic liquid of acidic quaternary phosphonium salt type was synthesized to instead of sulfuric acid was investigated,and it with Pt/C form bi-catalyst system and was used for the one step synthesis of p-aminophenol by catalytic hydrogenation of nitrobenzene.Among the four acidic quaternary phosphonium salt ionic liquids,catalytic performance of [HSO3(CH2)4P(Ph)3]HSO4 is superior to [HSO3(CH2)4P(Ph)3]CF3SO3,[HSO3(CH2)4P(Ph)3]CH3(C6H4)SO3 and [HSO3(CH2)4P(C4H9)3]HSO4.Under the reaction conditions of 85 ℃,0.2 MPa,4 h,Pt/C 0.2 g,NB 3.5 g,Ils 40 mL(m(IL)/m(NB)=7),1 000 r/min,nitrobenzene conversion was 86.54% and paminophenol yield was 48.98%.The experimental results indicated that the bi-catalyst system can be reused. |
