26, 209 TITLE: IMPROVED CATALYST PREPARATION METHOD ABSTRACT OF THE DISCLOSURE Copper-magnesium silicate-carbonate catalysts of improved activity and catalyst life for use in continuous hydration of acrylonitrile to acrylamide are prepared by a novel method in which magnesium and copper are precipitated separately in a common mother liquor and the precipitate is separated and dried at 170° - 200°C. before pelleting. Pellets made from the dried powder, when reduced and calcined for use in the hydration reaction have better combination of catalytic properties than prior art catalysts of the type.
