Applications and Usages : It is used as a quenching agent for various steels in the mechanical industry. Electroplating industry as copper, silver, cadmium and zinc, etc. In the metallurgical industry for the extraction of gold, silver and other precious metals. Chemical industry is the production of various inorganic cyanide and hydrocyanic acid raw materials, also used in the production of organic glass, a variety of synthetic materials, nitrile rubber, synthetic fiber copolymer. The dye industry is used in the manufacture of cyanogen chloride (reactive dye intermediate, and a raw material for the production of whitening agents). In the pharmaceutical industry for the manufacture of methyl cyanoacetate and malonic acid Diethyl ester. It is used as mordant in textile industry, and also used for liquid carburizing and nitriding of steel. Direct use of sodium cyanide production of important inorganic cyanide is mainly yellow blood salt sodium, yellow blood salt potassium, potassium cyanide, zinc cyanide, barium cyanide, cuprous cyanide, sodium thiocyanate, potassium thiocyanate; Organic cyanide is cyanoacetic acid, malononitrile, methionine, Benzyl Cyanide, cyanogen chloride, etc. The main products of hydrogen cyanide reproduction using sodium cyanide are: methyl methacrylate, Butyl methacrylate, methacrylic acid, azobisisobutyronitrile, azobisisoheptanitrile, nitrilotriacetic acid, hydroxyacetonitrile and so on.
