Copper cyanide, also known as Copper (I) cyanide, Cuprous cyanide, copper cyanide, cupricin, is an inorganic chemical with a white or yellowish powder appearance, slightly soluble in water but soluble in ammonia, KCN and insoluble in ethanol. Widely used in electroplating, catalyst in inorganic synthesis, as reagent…

Important Properties of Copper Cyanide
– They are solid, white or yellowish in color.

– Molecular mass: 89.563 g/mol

– Density is: 2.92 g/cm3

– Melting point: 474 °C (885 °F, 747 K)

– CuCN is almost insoluble in water, with a solubility of 0.00005g/100ml at 20oC

– They are only soluble in alkaline solutions, potassium cyanide and ammonia.

How is Copper Cyanide produced?
Copper cyanide is produced in large quantities by the reaction between copper sulfate and sodium cyanide:

2CuSO4 + 4NaCN → 2CuCN + (CN)2 + 2Na2SO4

Important applications of copper cyanide today
– Copper cyanide is used mainly for the electroplating industry:

CuCN is an indispensable chemical in copper electroplating, it acts as a catalyst in copper plating technology. Used to plate copper on iron, creating a protective layer on the metal surface, mainly used in plating red copper, brass, antique copper, imitation gold…

– Used as a reagent in the preparation of nitriles especially Gilman’s reagent.

Notes on use and storage of copper cyanide chemicals

Notes on storage of copper cyanide
– Copper cyanide placed in the workplace must be stored carefully to avoid polluting the environment and affecting people around.

– Keep them in cool, dry places, away from direct sunlight.

– Chemical warehouses must be separated to avoid chemical leakage or spillage causing pollution.

– Chemical storage warehouses must be located far from residential areas, away from water sources, places that store water for daily life or cultivation because it will seriously affect health.

What should be noted when using copper cyanide?
When exposed to copper cyanide chemicals in particular and other electroplating chemicals in general, it is necessary to equip yourself with appropriate tools and full protective equipment.
