Copper(I) Cyanide Usage :  Copper(I) cyanide, CuCN, [544-92-3], MW 89.56, MP 474°C, d 2.92, is white when pure, but usually available as an off-white or cream-colored powder and is insoluble in water and dilute acids but dissolves in complexing media such as ammonia and alkali cyanide solutions. Copper(I) cyanide is used in copper plating of nickel, chromium, zinc alloys, steel, and other metals or alloys.  Such copper plating imparts brightness, smoothness, hardness, and strength.  The cyanide solution employed for copper electroplating consists of copper cyanide and sodium cyanide.  Other applications of this compound are as an insecticide, a catalyst in polmerization, and as an antifouling agent in marine paints. Copper(I) cyanide is commonly used as a polymerization catalyst.  The compound is useful in organic synthesis, as a catalyst, reagent in the preparation of nitriles(sandmeyer reaction).  It is also used in electroplating copper and iron, silver plating, brass plating, and copper-tin alloy plating.  It is used to make phthalocyanine dyes and pigments. Cuprous cyanide is used in electroplating;  as an insecticide and fungicide;  and as a catalyst for polymerization.     In electroplating Cu or Fe;  as insecticide, fungicide;  as antifouling agent in marine paints;  as polymerization catalyst.
