Barium(2+) peroxide

Barium(2+) peroxide is an inorganic chemical compound with the formula BaO2 and CAS number 1304-29-6. This barium salt has a molecular weight of 169.33 g/mol and belongs to the peroxide family. It is classified as a solid oxidizing agent (Ox. Sol. 2) with acute toxicity properties. The compound appears as a white to grayish crystalline powder and is primarily used in industrial applications requiring strong oxidizing properties.

Barium(2+) peroxide is a white to light gray crystalline solid at room temperature with no characteristic odor. The compound is sparingly soluble in water and decomposes upon contact with moisture, releasing oxygen. It has a high melting point and demonstrates strong oxidizing properties due to its peroxide structure. The substance is denser than water and can release oxygen when heated or in contact with organic materials or reducing agents.

Barium(2+) peroxide is primarily used as an oxidizing agent in various industrial processes and chemical synthesis. It serves as a source of oxygen in pyrotechnic compositions and serves as a bleaching agent for certain materials. The compound is also utilized in the production of hydrogen peroxide and as an analytical reagent in laboratory applications. Its strong oxidizing properties make it valuable in specialized chemical manufacturing processes.

Barium(2+) peroxide requires careful handling due to its oxidizing and toxic properties (Acute Tox. 4). Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work in well-ventilated areas or under fume hoods to avoid inhalation. Keep the substance away from combustible materials, reducing agents, and sources of ignition. Use non-sparking tools and avoid generating dust during handling operations.

Barium(2+) peroxide must be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly sealed and protect from moisture, as the compound decomposes in humid conditions. Store separately from combustible materials, organic compounds, reducing agents, and acids. Use appropriate secondary containment and ensure storage areas are equipped with suitable fire suppression systems. Regular inspection of containers for signs of deterioration is recommended.

Immediate action is required due to the acute toxicity of barium(2+) peroxide. For skin contact, remove contaminated clothing and rinse thoroughly with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move the person to fresh air and provide artificial respiration if necessary. For ingestion, do not induce vomiting and seek immediate medical attention while providing supportive care.

Barium(2+) peroxide disposal must comply with local and national hazardous waste regulations due to its oxidizing and toxic properties. The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal companies. Small quantities should be neutralized carefully under controlled conditions before disposal. Always consult local environmental authorities for specific disposal requirements and approved waste management facilities in your region.

Barium(2+) peroxide is classified under ADR as Class 5.1 (Oxidizing substances), Packing Group II, indicating moderate danger during transport. Packages must meet UN specification requirements and display appropriate hazard labels including oxidizing agent markings. Vehicles must carry appropriate emergency equipment and drivers require ADR certification. The substance must be segregated from incompatible materials during transport and proper shipping documentation must accompany all shipments.

Barium(2+) peroxide is regulated under various European legislation including CLP Regulation for classification and labeling, displaying GHS03 and GHS07 pictograms with the signal word 'Danger'. While not currently listed as an SVHC substance under REACH, it requires registration for commercial use above certain tonnages. Users must comply with occupational safety regulations and may need special permits depending on quantities and applications in different EU member states.
