Understanding Glycerol (CAS 56-81-5): Properties and Safe Handling for Industrial Use
Glycerol, identified by its CAS number 56-81-5, is a fundamental chemical compound whose properties make it invaluable across numerous industrial applications. Understanding its chemical characteristics and adhering to safe handling practices are crucial for maximizing its utility and ensuring operational safety. NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality Glycerol and emphasizes the importance of proper management.
Chemically, Glycerol is a simple polyol, a type of alcohol containing multiple hydroxyl groups. Its molecular formula is C3H8O3, with a molecular weight of approximately 92.09 g/mol. At room temperature, it presents as a clear, colorless, viscous liquid with a sweet taste and virtually no odor. Its hygroscopic nature means it readily absorbs moisture from the atmosphere, which is key to its function as a humectant in various products. The high polarity conferred by its hydroxyl groups makes Glycerol highly soluble in water and polar organic solvents like ethanol, but only slightly soluble in non-polar solvents such as ether or chloroform.
From a safety and handling perspective, Glycerol is generally considered non-toxic and safe. However, like any chemical, it requires appropriate handling. Due to its hygroscopic nature, it should be stored in tightly sealed containers to prevent moisture absorption, which can affect its purity and concentration. Recommended storage temperatures often range from ambient to slightly elevated conditions, as indicated by product specifications, to maintain its liquid state and prevent degradation. For bulk industrial use, proper ventilation in storage areas is advisable, although Glycerol itself has a very low vapor pressure, minimizing inhalation risks under normal conditions. Adhering to these storage recommendations is vital for maintaining product quality and for those looking to buy Glycerol in significant quantities.
While Glycerol itself is relatively stable, it can react vigorously or even explosively with strong oxidizing agents such as potassium permanganate or chromium trioxide. It is incompatible with these substances and should be stored separately. Accidental mixing can lead to hazardous reactions. Industrial users must be aware of these incompatibilities to ensure safe storage and handling protocols are in place, especially when dealing with large volumes.
NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing comprehensive information alongside our high-quality Glycerol products. By understanding its chemical properties and following recommended handling and storage guidelines, industries can confidently and safely integrate Glycerol into their processes, whether for manufacturing, research, or product formulation. Our dedication to quality extends to ensuring our clients have the knowledge to use our products effectively and safely.
