Nickel(2+) dinitrite

Nickel(2+) dinitrite is an inorganic chemical compound with the molecular formula N2NiO4 and CAS number 17861-62-0. This compound consists of nickel in its +2 oxidation state combined with two nitrite ions (NO2-). With a molecular weight of 150.7 g/mol, it belongs to the class of nickel salts and exhibits oxidizing properties, which classifies it under ADR class 5.1 for transportation purposes.

Nickel(2+) dinitrite typically appears as a crystalline solid at room temperature. Like most nickel compounds, it likely exhibits a characteristic green or blue-green coloration. The compound contains nitrite groups which make it an oxidizing agent. Its molecular weight is 150.7 g/mol, and it should be expected to have some degree of water solubility given its ionic nature, though specific solubility data would need experimental verification.

Nickel(2+) dinitrite is primarily used in specialized chemical applications where both nickel ions and nitrite functionality are required. It may serve as a precursor in the synthesis of other nickel compounds, as a catalyst or catalyst precursor in certain chemical reactions, and potentially in electroplating or surface treatment processes. Its oxidizing properties make it useful in specific industrial processes requiring controlled oxidation reactions.

Nickel(2+) dinitrite should be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume extraction to avoid inhalation of dust particles. As an oxidizing agent (ADR class 5.1), keep away from combustible materials, reducing agents, and heat sources. Use non-sparking tools and ensure proper grounding when handling to prevent static electricity buildup.

Nickel(2+) dinitrite should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. As a class 5.1 oxidizing agent, it must be kept separate from flammable materials, reducing agents, and organic compounds. Use appropriate containers that are compatible with oxidizing agents, and ensure proper labeling. Storage areas should be equipped with suitable fire suppression systems and spill containment measures.

In case of skin contact with nickel(2+) dinitrite, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms develop.

Nickel(2+) dinitrite must be disposed of as hazardous chemical waste in accordance with local, national, and EU regulations. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil. The compound requires special handling due to its oxidizing properties and nickel content. Maintain proper documentation of waste disposal and follow all applicable environmental protection guidelines.

Nickel(2+) dinitrite is classified under ADR class 5.1 (oxidizing substances) group III for transportation purposes. It must be packaged in UN-approved containers suitable for oxidizing agents and properly labeled with appropriate hazard placards. Transportation vehicles must comply with ADR requirements for class 5.1 substances, including proper segregation from incompatible materials and appropriate emergency equipment. Drivers require ADR certification for transporting oxidizing substances.

Nickel(2+) dinitrite is subject to various chemical regulations including REACH registration requirements in the European Union. While it is not classified as a Substance of Very High Concern (SVHC), users must comply with CLP regulation for classification, labeling, and packaging. Industrial users should check for any sector-specific restrictions and ensure proper safety data sheet availability. Regular regulatory updates should be monitored as nickel compounds are subject to ongoing regulatory scrutiny.
