Magnesium peroxide

Magnesium peroxide is an inorganic chemical compound with the formula MgO2 and CAS number 14452-57-4. It has a molecular weight of 56.304 g/mol and serves as an oxidizing agent in various industrial applications. This white crystalline solid releases oxygen when it decomposes, making it valuable in applications requiring controlled oxygen release or bleaching properties.

Magnesium peroxide is a white to off-white crystalline powder that is odorless and stable under normal conditions. It is sparingly soluble in water but decomposes slowly in aqueous solutions to release oxygen and form magnesium hydroxide. The compound is thermally stable but decomposes at elevated temperatures, releasing oxygen gas and forming magnesium oxide.

Magnesium peroxide is used as an oxidizing agent in various industrial applications including bleaching processes, environmental remediation, and as an oxygen source in soil conditioning. It finds application in textile processing, paper manufacturing, and water treatment systems. The compound is also utilized in agricultural applications for soil aeration and in some specialized chemical syntheses requiring controlled oxygen release.

Magnesium peroxide should be handled with standard laboratory safety equipment including safety glasses, gloves, and protective clothing. Work in well-ventilated areas to prevent dust accumulation and avoid contact with incompatible materials such as reducing agents and organic materials. Use appropriate dust control measures and ensure personnel are trained in handling oxidizing substances to prevent fire or explosion hazards.

Magnesium peroxide should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed and store separately from reducing agents, combustible materials, and organic substances. The storage area should be designed for oxidizing materials and equipped with appropriate fire suppression systems. Regular inspection of storage containers is recommended.

In case of skin contact with magnesium peroxide, immediately remove contaminated clothing and wash the affected area with plenty of water for at least 15 minutes. For eye contact, flush immediately with water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Magnesium peroxide disposal must comply with local and national waste regulations as it is classified as an oxidizing substance. Contact licensed waste disposal companies experienced in handling oxidizing materials. Small quantities may be neutralized by careful dissolution in water under controlled conditions, but this should only be done by trained personnel. Never dispose of in regular waste streams or mix with organic materials.

Magnesium peroxide is classified under ADR as Class 5.1 (Oxidizing substances) Packing Group II, requiring specific packaging and labeling requirements for transport. Use UN-approved packaging suitable for oxidizing substances and ensure proper documentation including transport documents and emergency response information. Vehicles must be equipped according to ADR regulations and drivers must hold appropriate dangerous goods certificates.

Magnesium peroxide is regulated under various chemical safety frameworks including REACH registration requirements in Europe and CLP classification for oxidizing properties. It is not listed as a Substance of Very High Concern (SVHC) under REACH. Transport is regulated under ADR/RID/ADN as a Class 5.1 oxidizing substance, and workplace exposure limits may apply depending on national regulations.
