Chemical Name: Polyphosphoric acid Alias: tetraphosphate Molecular formula: H6P4O13 (approximate) Appearance: colorless, viscous liquid, deliquescent Molecular Weight: 337.93 Vapor Pressure Boiling point: 856 Solubility: miscible with water Density: relative density (water = 1) 2.1 Stability: Stable CAS NO: 8017-16-1 Polyphosphoric acid hazards Polyphosphoric acid in pathways mainly inhaled, ingested, percutaneous absorption. Health hazards are as follows: The product is limited information on the health effects. Skin or eye contact may cause burns. If breathing vapor or mist may produce respiratory tract irritation and damage effects. Polyphosphoric acid hazardous characteristics: corrosive. Produce toxic phosphorus oxide gas. Combustion (decomposition) products: phosphorus oxide, phosphine. For emergency treatment and disposal methods Leakage contingency Leak contaminated areas evacuated personnel to a safe area, not to prohibit access to the contaminated area, the proposed emergency personnel wearing gas masks, chemical protective clothing to wear. Do not direct contact with leakage, in ensuring the safety of plugging. Use sand, vermiculite or other inert materials to absorb, and then collect and transport the waste to disposal sites. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound. Protective measures Respiratory protection: its possible exposure to vapor, must wear gas masks or gas-helmet. Emergency rescue or evacuation, it is recommended to wear self-contained breathing apparatus. Eye protection: Wear protective chemical safety glasses. Protective clothing: wearing overalls (anti-corrosion material). Hand protection: Wear rubber gloves. Other: after working, take a shower. Separate storage of toxic pollution by the clothes, washed reuse. To maintain good health habits. Emergency measures Skin contact: Immediately flush with water for at least 15 minutes. If it burns, medical care treatment. Eye contact: immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Inhalation: from the scene to fresh air. Artificial respiration if necessary. Doctor. Fresh into: coverage immediately mouthwash, or egg white to the blues. Doctor.
