| Abstract: | A new kind of Raney Ni catalyst was prepared from rapidly solidified NiAlSiFeCe alloy precusor.Cross experimentation was carried out to optimize the reaction conditions for fatty nitrile hydrogenation to primary amine catalyzed by this new catalyst. The results show that the new catalyst produces favourable catalytic properties under the conditions of P H 2 =3.0 MPa, P NH 3 =0.9 MPa, T =428 K, t =1.50 h,Cat./RCN=0.5%(wt.-wt.%) within the adjusting margin, the corresponding convertion ratio of fatty nitrile and selectivity of primary amine are up to 99.07% and 99.41% respectively. |
