flame retardant chemica Phosphorus pentoxide P2O5

flame retardant chemica Phosphorus pentoxide P2O5
Product Detailed
Phosphorus pentoxide white powder, relative density of 2.39g / cm, point 580-585 C, 300 degrees C sublimation

The fundamental condition introduces:1 aliases: phosphoric anhydride2 molecular formula: P4O10 ( general writing: P2O5 )3: 1.41.94 molecular weightClassification and numbering 4:The GB8.1 class 81063. The original iron rule : the level of inorganic acid corrosive goods. In 91034, UNNO: 1807. The IMDG CODE 8198 page, 8 class.Chemical formula: P2O5 5The 6 production methods:CombustionP + oxygen of phosphorus pentoxide4P+5O = 2P2O5Main uses:Phosphorus pentoxide is chemical supplies of raw materials and reagents, the products are widely used in pharmaceutical, paint additives, textile auxiliaries, antistatic agent, coupling agent of organic titanate, three phosphorus chemical industry. Mainly used in the manufacture of high purity phosphoric acid, used as a gas and liquid desiccant dehydration machine, organic synthesis, and preparation of organic phosphate.Physical property.Usually white easily deliquescent soluble crystalline powder, density of 0.9g / cm, at 300 degrees 580-585 degrees sublimation, melting point, the vapor pressure of 133.3pa (384 degrees C ). Under pressure in a heating to a higher temperature, crystal transform into amorphous glass shaped body, easy to absorb moisture in the air, soluble in water, giving off heat and smoke.Storage and transport conditions:Corrosion method for packaging: ( II ). Stored in a cool, dry, ventilated warehouse. With the combustible, alkali isolated storage, handling light light unloading, prevent damage, must be sealed containers, prevent rain and moisture. Leakage treatment: wearing gas masks and gloves, soda or the equivalent amount of low alkali and slaked lime mixture and uniform, made of mud, follow the tide into the large amounts of water, neutralization and diluted into the wastewater system. Easy water reaction of phosphoric acid.Warranty period of 5 to September can be stored for 30 days; October to April period can be stored for 60 days, in a closed barrel can be stored for 6 months.Specifications and quality standards: ( GB / T2305-2000 )Project indicators of industrial grade ( chemical ), analysis of pure content indexContent ( P2O5 ) > 98% > 98.5% > 99% > 99.2%Activity of R 1.2-1.7 3-5Also the original ( P2O3 ) % = 0.01% = 0.008% = 0.008 = 0.006%Clarity test transparent, no precipitationWater insoluble = 0.02% = 0.01% = 0.01% = 0.007%The total amount of ammonia ( N ) = 0.01% = 0.002% = 0.01% = 0.002%Heavy metal ( Pb ) = 0.01% = 0.002% = 0.01% = 0.002%Iron content ( Fe ) = 0.01% = 0.002% = 0.008% = 0.002%Phosphorus ( As ) = 0.005% = 0.007% = 0.005% = 0.003%
