Reliable data

Used as a quenching agent for various steels in the mechanical industry. As the main component of copper, silver, cadmium and zinc plating in the electroplating industry. Used to extract precious metals such as gold and silver in the metallurgical industry. It is a raw material for the manufacture of various inorganic cyanides and the generation of hydrocyanic acid in the chemical industry. It is also used to manufacture organic glass, various synthetic materials, nitrile rubber, and copolymers of synthetic fibers.

In the dye industry, it is used to manufacture cyanuric chloride (an intermediate for reactive dyes and a raw material for the production of whitening agents). In the pharmaceutical industry, it is used to manufacture methyl cyanoacetate and diethyl malonate. It is used as a mordant in the textile industry and is also used for liquid carburizing and nitriding of steel.

Important inorganic cyanides produced directly from sodium cyanide include sodium cyanide, potassium cyanide, potassium cyanide, zinc cyanide, barium cyanide, cuprous cyanide, sodium thiocyanide, potassium thiocyanide; organic cyanides include cyanoacetic acid, malononitrile, methionine, benzyl cyanide, cyanuric chloride, etc.

The main products produced by using sodium cyanide to generate hydrogen cyanide include: methyl methacrylate, butyl methacrylate, methacrylic acid, azobisisobutyronitrile, azobisisoheptanenitrile, nitrilotriacetic acid, hydroxyacetonitrile, etc.
