Application:
Sodium cyanide is an important basic chemical raw material used in basic chemical synthesis, electroplating, metallurgy, and organic synthesis of pharmaceuticals, pesticides, and metal processing. Chelating agents, masking agents. Extraction and electroplating of precious metals such as gold and silver.
Used as a quenching agent for various steels in the mechanical industry.
As the main components of copper plating, silver, cadmium, and zinc in the electroplating industry. In the electroplating solution, the anodic polarization effect can be reduced, ensuring the normal dissolution of the anode, stabilizing the plating solution, and improving the cathodic polarization effect, resulting in a uniform coating.
Used in the metallurgical industry for extracting precious metals such as gold and silver.
In the chemical industry, it is used as a raw material for the production of various inorganic cyanides and hydrogen cyanide, as well as for the production of organic glass, various synthetic materials, nitrile rubber, and copolymers of synthetic fibers.
Used in the dye industry to manufacture cyanuric chloride (an intermediate of reactive dyes and a raw material for producing whitening agents).
Used in the pharmaceutical industry for the production of methyl cyanoacetate and diethyl malonate. Used as a mordant in the textile industry, and also for liquid carburizing and nitriding of steel.
The important inorganic cyanides produced directly from sodium cyanide include sodium ferrocyanide, potassium ferrocyanide, potassium cyanide, zinc cyanide, barium cyanide, cuprous cyanide, sodium thiocyanate, and potassium thiocyanate; Organic cyanides include cyanoacetic acid, malononitrile, methionine, benzyl cyanide, cyanuric chloride, etc. The main products produced through the production of hydrogen cyanide using sodium cyanide include: methyl methacrylate, butyl methacrylate, methyl acrylic acid, azodiisobutyronitrile, azodiisobutyronitrile, triaminoacetic acid, hydroxyacetonitrile, etc.
