phosphorus pentoxide usage and synthesis
outline also known as phosphoric anhydride, phosphorus pentoxide is phosphorus oxides generated by combustion of white phosphorus, yellow or red phosphorus in dry air, soft white powder or colorless monoclinic crystal at room temperature, easily deliquescence, melting point is 580 ~ 585 ℃, relative density is 2.39, sublimation is 347 ℃. when heated under pressure to 563 ℃, crystalline substance translates to amorphous glass (melt). it is insoluble in acetone, ammonia, soluble in sulfuric acid. it is easy to absorb moisture in the air, easy to absorb moisture, and have a strong dehydration, can even dehydrate concentrated sulfuric acid to produce sulfur trioxide, is a potent desiccant, reacts violently with water and emits heat and white smoke. per mole of phosphorus pentoxide releases 68 kilocalories, usually generate metaphosphate with cold water, and generate mainly phosphoric acid with hot water. according to the amount of water added, it can generate different pentavalent phosphorus oxyacid, such as metaphosphoric acid, pyrophosphoric acid, orthophosphoric acid, etc. it is used to make high purity phosphoric acid, as well as gas and liquid desiccant, organic synthetic dehydrating agent.
risk category class 8.1 acidic corrosive product
hazardous characteristics non-combustible. but encountering water and organic materials such as wood, cotton or straw, it reacts violently to release heat, may cause a fire. contacting water, it can emit a lot of smoke and heat. the case of the moisture, it corrodes most metals slightly. a strong local irritation, vapor with dust can severely irritate the eyes, mucous membranes, skin and respiratory system, and corrode the skin, mucous membranes. even the dust concentration of 1mg / m3, it is unbearable.
the above information is edited by the chemicalbook of yan yanyong.
