Abstract
Homogeneous catalyst for hydration of nitriles to produce amides comprises reduced copper with at least 0.2 percent by weight of reduced iron. Preferred catalysts prepared by reduction of copper and iron compounds with borohydride reducing agent have improved stability of catalytic activity during storage as compared with copper catalysts made without iron.
