Phosphorus Pentoxide(50kg metal pail) 1. Another name: anhydrous phosphoric acid2. Molecular formula:P2O53. Molecular weight: 141.944.Classification of hazardous materials: GB8.1-81063. IMDG CODE p8198,8 5.Uses: Phosphorus pentoxide is usual material and reagent in chemical industry, this product is widely used in the industries of medicine, coating auxiliaries, printing and dyeing auxiliaries, anti static additive, titanate coupling agent, phosphorus oxychloride, chemical.Mainly used in producing high purity phosphoric acid, used as desiccant of gas and liquid, dehydrant of organic synthesis.6.Properties: very deliquescent, density 0.9g/cm3,mp. 580-585oC, sublimation temperature 300oC, vapor pressure 133.3Pa (384oC). May transform to amorphous from under elevated temperature and pressure. Readily absorbs moisture from. Exothermic hydrolysis by water to yield phosphoric acid.7.Hazards Identification: Non-flammable. Reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat and may even cause fire. Corrosive to metal. Very irritating. May cause severe burn to eye, skin, mucosa and respiratory tract even at as low as 1mg/cm3.8.Fire fighting measures: Wear full protective gear. Do NOT use water directly on fire. Use dry chemical, carbon dioxide, or alcohol-resistant foam.First aid measures: Inhalation: Remove from exposure to fresh air immediately. Get medical aid.Eye: Flush eyes with plenty of water for at least 15 minutes. Ger medical aid.Skin: Flush skin with plenty of water. Get medical aid.Labeling: Corrosive9.Storage & Handling: Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water, metals, alkali and flammable substances Handle with care. Keep containers tightly closed. Avoid moisture.10.Accidental Release Measures: Wear full protective gear. Neutralize the spills with a mixed solution of sodium bicarbonate and calcium hydroxide.11.Specifications & Technical Data: Reduced (P2O3) ≤0.01 Water insoluble matter ≤0.02 Heavy metals with (the Pb allounts) ≤0.01 Fe ≤0.01 As ≤0.01
