Cupreous catalysts containing (a) copper prepared by reducing copper oxide, (b) reduced copper oxide, or (c) copper oxide have been found to be excellent heterogeneous catalysts for the conversion of nitriles in the presence of water to the corresponding amides. High conversions and yields are obtained with little or no deleterious by-products.

Catalysts for the hydration of nitriles to amides

An improved electroconductive resin composition is obtained by using a water-dispersible, film-forming acrylamide polymer as a binder and extender for a water-soluble quaternary ammonium electroconductive resin. Particularly useful is a self-binding blend of about 65-95 wt. % polyvinylbenzyltrimethylammonium chloride and about 5-35 wt. % nonhydrolyzed polyacrylamide which can be formulated as an aqueous dispersion with clay or other printing pigments. Applied to a nonmetallic substrate, such as paper or an organic polymer film, the improved electroconductive resin composition reduces the surface electrical resistivity of the substrate and also provides improved holdout to aromatic and aliphatic solvents.
