説明off-white to green powder. Insoluble in water,soluble in HCI, Nl40H, and potassium cyanide. Used in Sandmeyer's reaction to synthesize aryl cyanides. Toxic by skin absorption, through open wounds, by ingestion, and by inhalation of hydrogen cyanide that arises from slight decomposition. Produces toxic oxides of nitrogen in fires.

使用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.

合成方法硫酸銅（Ⅱ）溶液にシアン化ナトリウムを加え，ジシアンガスを脱気して析出させる，または塩化銅（Ⅰ）溶液にシアン化ナトリウムを作用させる

純化方法Wash the cyanide thoroughly with boiling H2O, then with EtOH. Dry it at 100o to a fine soft powder. It dissolves in excess alkali cyanide solutions to form the very soluble complex ion Cu(CN)43-. [Bassett & Corbett J Chem Soc 125 1660 1924, Barber J Chem Soc 79 1943.]
