Abstract

An oxidic composition which is suitable as a catalyst having divalent and trivalent iron in an atomic ratio of divalent to trivalent iron in the range from greater than 0.5 to 5.5 and oxygen as a counterion to the divalent and trivalent iron. The catalyst composition is useful in the hydrogenation of nitriles to amines.
