摘要： When making an a amide by hydrolysis of a nitrile in an aqueous medium containing a Raney copper catalyst, the yield of amide can be increased and the yield of impurities can be decreased by including vanadium metal in the catalyst. The vanadium may be present as Raney vanadium often as an alloy in the Raney copper.

摘要： When making an amide by hydrolysis of a nitrile in an aqueous medium containing a Raney copper or other black copper catalyst, the hydrolysis reaction can be improved if the catalyst has been contacted with an aqueous solution of a water soluble vanadium compound followed by thorough rinsing before introduction into the aqueous medium.
