Abstract: The invention relates to a method for hydrocyanating an olefinically unsaturated nitrile in the presence of a catalyst that contains Ni(0). The inventive method is characterized in that the reaction is carried out in the presence of a hydrocarbon that, under certain pressure, concentration and temperature conditions, leads to the formation of at least two liquid phases of the overall system of which one phase, with regard to the overall weight of the phase, has a higher proportion of the catalyst containing Ni(0) than the other phase or other phases.
