Overview

Magnesium diperchlorate (CAS 10034-81-8) is an inorganic oxidizing salt with strong hygroscopic properties and high solubility in water. This white crystalline compound represents an important member of the perchlorate family, distinguished by its exceptional ability to absorb moisture from the atmosphere. With the molecular formula Cl2MgO8 and a molecular weight of 223.2 g/mol, magnesium diperchlorate exhibits remarkable stability under normal conditions while maintaining powerful oxidizing characteristics that classify it under ADR class 5.1 for transportation purposes. The compound's most notable property is its extreme hygroscopicity, making it highly effective as a desiccant in various industrial applications. Unlike many other drying agents, magnesium diperchlorate can achieve extremely low residual water content, making it particularly valuable in analytical chemistry and specialized drying processes. Its high water solubility and ability to form stable hydrates contribute to its effectiveness in moisture control applications. Safety considerations for magnesium diperchlorate primarily relate to its oxidizing nature, which requires careful handling and storage away from combustible materials and reducing agents. While not classified with specific GHS pictograms, proper industrial safety protocols should be observed during handling and storage operations. Industrial applications include use as a specialized desiccant in gas drying systems, analytical chemistry procedures requiring anhydrous conditions, and certain specialized chemical synthesis processes where extremely low moisture content is critical. In analytical applications, it often serves alongside other inorganic salts such as calcium dichlorate dihydrate in comparative moisture control studies. OYSI offers magnesium diperchlorate as part of our comprehensive portfolio of specialized inorganic chemicals for European industrial customers.

Frequently Asked Questions

What is magnesium diperchlorate?

Magnesium diperchlorate is an inorganic chemical compound with the formula Cl2MgO8 and CAS number 10034-81-8. This perchlorate salt has a molecular weight of 223.2 g/mol and consists of magnesium cations paired with perchlorate anions. It is classified as an oxidizing substance due to its perchlorate content, which can readily release oxygen and support combustion reactions.

What are the physicochemical properties of magnesium diperchlorate?

Magnesium diperchlorate is a white crystalline solid that is highly hygroscopic, meaning it readily absorbs moisture from air. It exhibits excellent water solubility, dissolving readily in aqueous solutions. The compound is stable under normal conditions but can decompose at elevated temperatures, releasing oxygen. Its oxidizing nature makes it reactive with organic materials and reducing agents.

What is magnesium diperchlorate used for?

Magnesium diperchlorate is primarily used as a powerful desiccant and dehydrating agent in laboratory applications due to its exceptional hygroscopic properties. It serves in analytical chemistry for moisture removal from gases and organic solvents. The compound also finds applications in pyrotechnics and explosive formulations as an oxidizing agent, and in specialized industrial processes requiring controlled oxidation reactions.

How to handle magnesium diperchlorate safely?

Magnesium diperchlorate requires careful handling using appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas to avoid dust inhalation. Keep away from heat sources, flames, and combustible materials due to its oxidizing properties. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup during handling operations.

How to store magnesium diperchlorate correctly?

Magnesium diperchlorate must be stored in tightly sealed, moisture-proof containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep separate from combustible materials, organic compounds, and reducing agents to prevent dangerous reactions. Store in original containers with proper labeling and maintain ambient temperatures below 30°C to ensure stability and prevent decomposition.

What to do in case of contact with magnesium diperchlorate?

Magnesium diperchlorate contact requires immediate action depending on exposure route. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. If inhaled, move to fresh air immediately. For eye contact, flush thoroughly with water and seek medical attention. In case of ingestion, do not induce vomiting and seek immediate medical assistance.

How to dispose of magnesium diperchlorate appropriately?

Magnesium diperchlorate disposal must comply with local and national hazardous waste regulations as it is classified as an oxidizing substance. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Do not discharge into drains, waterways, or regular waste streams. Small laboratory quantities may require neutralization before disposal, following institutional waste management protocols and environmental guidelines.

How to transport magnesium diperchlorate?

Magnesium diperchlorate is classified under ADR Class 5.1 (Oxidizing substances) Group II for transport purposes. It must be packaged in appropriate UN-approved containers with proper labeling and documentation. Transport vehicles require oxidizing substance placards and emergency response information. Drivers need specialized training for dangerous goods transport, and shipments must comply with quantity limitations and routing restrictions.

Is magnesium diperchlorate subject to particular regulations?

Magnesium diperchlorate is subject to various chemical regulations including REACH registration requirements in Europe and classification under the CLP Regulation as an oxidizing substance. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational safety regulations, transport classifications, and local environmental protection laws governing oxidizing chemicals.
