摘　　要：The p-chloroaniline was prepared by catalytic hydrogenation reduction of p-chloronitrobenzene in the presence of Raney Ni and trienthylphosphite in water.The results showed that the catalystic system consisting of Raney Ni and trienthylphosphite(TEP) which could be reused present effective catalytic activity and selectivity.The conversion of p-chloronitrobenzene was 100% and the yield was over 98% with a selectivity of p-chloroaniline over 99% compared with the yield of about 88% with-out TEP in the eatalytic system when the reaction temperature was 90℃ and reaction time was 2h.
