Abstract
An electrochemical method is provided for maintaining the optimum activity of copper-containing catalysts for the production of amides from nitriles and water. Also provided is a process for producing amides from nitriles and water by hydrolysis.
Claims5
A process for the production of amides from nitriles in water comprising:
- contacting an electrolytic solution of nitrile in water in an electrochemical reactor having at least one copper-containing electrode wherein said copper-containing electrode has at least a partial surface coverage of at least an average thickness of 0.75 monolayers of ionic copper, maintaining the pH of said electrolytic solution below 7, and
- applying a direct current to the electrochemical reactor.
