Calcium dicyanide

Calcium dicyanide is an inorganic chemical compound with the molecular formula C2CaN2 and CAS number 592-01-8. This substance has a molecular weight of 92.11 g/mol and belongs to the cyanide family of compounds. It is classified as highly toxic (Acute Tox. 2) and poses significant environmental hazards to aquatic life. The compound is regulated under various safety standards due to its dangerous properties and requires careful handling in industrial applications.

Calcium dicyanide appears as a white to off-white crystalline solid at room temperature. The compound is highly soluble in water, forming alkaline solutions that can release toxic hydrogen cyanide gas under acidic conditions. It has a molecular weight of 92.11 g/mol and is typically odorless in its pure form. The substance is hygroscopic, meaning it readily absorbs moisture from the atmosphere, which can affect its stability and handling characteristics.

Calcium dicyanide is primarily used in industrial applications as a source of cyanide ions for various chemical processes. It serves as an intermediate in the production of other cyanide compounds and can be utilized in certain metallurgical processes. The compound may also find applications in specialized chemical synthesis where controlled release of cyanide is required. Due to its high toxicity, its use is strictly regulated and limited to professional industrial settings with appropriate safety measures.

Calcium dicyanide must be handled with extreme caution due to its high toxicity classification (Acute Tox. 2). Essential personal protective equipment includes full-face respirators, chemical-resistant gloves, and protective clothing. Work should only be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Personnel must be trained in cyanide safety protocols, and emergency equipment including oxygen and antidotes should be readily available. Never handle this substance without proper safety training and equipment.

Calcium dicyanide must be stored in a cool, dry, well-ventilated area away from incompatible materials such as acids, oxidizing agents, and moisture. The storage area should be secured and accessible only to trained personnel. Containers must be tightly sealed and properly labeled according to GHS requirements with appropriate hazard pictogrammes (GHS06, GHS09). Storage facilities should include emergency response equipment and be designed to contain potential spills while preventing environmental contamination.

Immediate action is critical due to the substance's high toxicity. For skin contact, remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. If inhaled, move the victim to fresh air immediately and seek emergency medical attention. For eye contact, rinse thoroughly with water for at least 15 minutes. In all cases of exposure, contact emergency services immediately and inform them of cyanide exposure. Never induce vomiting if ingested.

Calcium dicyanide disposal must comply with local, national, and EU waste regulations due to its classification as hazardous waste. The substance cannot be disposed of through regular waste streams and requires specialized treatment by licensed hazardous waste disposal companies. Disposal methods typically involve chemical neutralization or high-temperature incineration in approved facilities. All disposal activities must be documented, and waste codes must be properly assigned according to the European Waste Catalogue.

Calcium dicyanide is classified under ADR Class 6.1 (Toxic substances), Packing Group I, indicating its high toxicity level. Transportation requires specialized packaging that meets UN specification standards and proper hazard labeling with appropriate placards. Only certified carriers trained in hazardous materials transport can handle this substance. Transport documentation must include proper shipping names, hazard classifications, and emergency response information. Vehicle ventilation and emergency equipment are mandatory during transport.

Calcium dicyanide is subject to extensive regulation under EU chemical legislation including REACH and CLP regulations. The substance requires safety data sheets and hazard communication due to its Acute Tox. 2 classification and environmental hazards (Aquatic Acute 1, Aquatic Chronic 1). While not currently listed as a SVHC (Substance of Very High Concern), its use may be restricted in certain applications. Industries using this chemical must comply with occupational exposure limits and environmental discharge regulations.

Calcium dicyanide is available through specialized chemical distributors like OYSI, which serves the European market with professional-grade chemical products. Due to the substance's high toxicity and regulatory requirements, purchases are typically restricted to qualified industrial users who can demonstrate proper handling capabilities and legitimate use applications. Buyers must provide appropriate documentation and comply with all relevant safety and regulatory requirements. Contact OYSI's technical team for availability and specific application guidance.
