Catalysts and their use in the hydrolysis of nitriles |
| abstract |
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. |
