The influence of supports of copper catalysts produced by the ion-exchange technique on SiO2, Al2O3 and TiO2 has been studied for the hydrolysis of acrylonitrile to acrylamide. Cu/SiO2 has been found to be the best catalyst, deactivating less rapidly than Cu/Al2O3. Metal-support effects were observed in Cu/TiO2 catalysts, both for carbon monoxide adsorption and acrylonitrile hydrolysis. The best Cu/TiO2 catalyst was less active than Cu/SiO2.
