1. one kind is passed through partial hydrogenation aliphatic series α

  • in the presence of catalyzer, and ω

    -two nitrile compounds prepares aliphatic alpha, the method for alpha, omega-amino nitriles, and described catalyzer;

    (a) contain iron or a kind of compound or its mixture based on iron;

    With(b) based on the weight meter of (a), contain 0.01-5% (weight) based on 2,3,4 or5 kinds of promotors that are selected from the element of aluminium, silicon, zirconium, titanium and vanadium;

    With(c) based on the weight meter of (a), a kind of of 0-0.5% (weight) is characterized in that based on basic metal or alkaline earth metal compounds, and used α

    , ω

    -two nitrile compounds contain 1.0ppm (weight) or more phosphorus.
