Phosphorous Pentoxide(P2O5)
Another name: anhydrous phosphoric acid
2. Molecular formula: P2O5
3. Molecular weight: **1.9
4 CAS:********3
Classification of hazardous materials: GB8.******3. IMDG CODE
Use: in synthesis of phosphorus oxychloride, metaphosphoric acid; in manufacture of acrylate, surface active agent; in refining of drugs and sugar; as dehydrating agent, desiccant, antistatic agent; analytical reagent.
Properties: White crystals, very deliquescent, density 0.9g/cm3,mp. ******5C, sublimation temperature **0C, vapor pressure **3.3Pa (**4C). May transform to amorphous from under elevated temperature and pressure. Readily absorbs moisture from. Exothermic hydrolysis by water to yield phosphoric acid.
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.
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.
