Sodium Cyanide

The main uses of Sodium Cyanide

Sodium cyanide (NaCN) is a highly toxic inorganic compound, but it has a wide range of applications in industry and other fields. The following is a detailed classification of its main uses:

1、 Main industrial applications

Electroplating industry:

Sodium cyanide is used as a complexing agent in the electroplating process, forming metal cyanide complex ions with the coating metalCan provide uniform coating to improve the appearance quality and wear resistance of metal products

At present, except for electroplating zinc, most metal electroplating (such as silver mirror production) still uses cyanide containing processes

Metallurgical industry:

Gold extraction: Cyanide leaching is the most efficient gold extraction method in the world, and China, as the largest producer of gold, widely uses this technology

Steel Heat Treatment: As a heat treatment agent, it can improve the mechanical properties (hardness, toughness) and corrosion resistance of steel

Chemical synthesis:

Used for synthesizing various organic compounds, it is an important chemical raw material for the production of methyl methacrylate and other compounds

Participate in various chemical reactions as a chelating agent and masking agent

Pesticide production:

Used for synthesizing various pesticides such as glyphosate, fenvalerate, and paraquat

As an intermediate in pesticides, such as 4-chlorophenylurea, an intermediate in the synthesis of insecticides such as imidacloprid

Dye production:

Can synthesize various dyes such as Yellow 139, Yellow 150, Indigo, Hualan, etc

Used for producing fluorescent whitening agent VBL, dispersed turquoise GL, etc

2、 Other important uses

Pharmaceutical industry:

It is a necessary raw material for the production of diethyl malonate, which is used to manufacture barbiturates and sulfonamide anti-inflammatory drugs

As an intermediate used in the production of various drugs such as penicillin, pregabalin, vitamin B6, etc

Textile industry:

As an important raw material for synthetic fibers, 70% of textile fiber production in China relies on sodium cyanide

Food industry:

Used to synthesize pear, apple, grape and other fruit essence
