Abstract
For making supported copper catalyst, useful in hydration of nitriles to produce amides, a cuprous compound e.g. cuprous chloride is impregnated into a support material, e.g. alumina, using acrylonitrile or acetonitrile as the imbibing solvent which is then removed by evaporation. The cuprous compound in the support is reduced to copper in situ, by contact with a reducing agent e.g. sodium borohydride.
