Sodium Cyanide

Sodium Cyanide

Chemical Formula: NaCN
CAS Number: 143-33-9
Appearance: White crystalline powder or granules, hygroscopic, with a faint bitter almond odor.

Key Features

• High Toxicity: Sodium cyanide is a highly toxic chemical and requires strict management.

• Water Solubility: Easily soluble in water, releasing hydrogen cyanide (HCN), which is highly toxic.

• Strong Reducing Agent: Exhibits strong reducing properties in chemical reactions, widely used in metallurgy and chemical industries.

• Stability: Relatively stable under dry conditions but releases hydrogen cyanide gas when exposed to acids or moisture.

• Wide Applications: Primarily used in gold extraction, electroplating, and chemical synthesis.

Applications

1. Metallurgical Industry

• Used for gold and silver extraction, separating precious metals from ores through the cyanidation process.

• Used in metal surface treatment, such as electroplating and galvanizing.

2. Chemical Industry

• Used as a key raw material in organic synthesis for producing cyanides, nitriles, and dyes.

• Used in the manufacture of pesticides and pharmaceutical intermediates.

3. Other Applications

• Used in chemical analysis in laboratories.

• Used in the synthesis of certain specialty materials.

Safety and Handling

• Storage: Store in a cool, dry, well-ventilated dedicated warehouse, away from acids, oxidizers, and flammable materials.

• Safety Precautions:

• Wear full protective equipment (e.g., gas masks, protective clothing, gloves, goggles) during handling.

• Avoid direct contact with skin, eyes, and inhalation of dust or gas.

• Emergency Measures:

• In case of leakage, immediately isolate the area and use specialized absorbent materials for cleanup.

• If skin or eye contact occurs, rinse immediately with plenty of water and seek medical attention.

• Transportation: Transport in accordance with regulations for highly toxic chemicals, using dedicated vehicles and equipped with emergency response equipment.

Key Advantages

• Efficient Extraction of Precious Metals: Indispensable in gold and silver extraction.

• Versatility: Widely used in metallurgy, chemical, and electroplating industries.

• High Purity: Industrial-grade sodium cyanide offers high purity and reaction efficiency.

Precautions

• Sodium cyanide is a highly toxic chemical; its handling and storage must strictly comply with relevant laws and regulations.

• Professional training is required before use to ensure operators are familiar with safety protocols and emergency measures.
