Description
Phosphorus trioxide, also known as phosphorus acid or phosphoric anhydride, is a white crystalline solid or a liquid with a melting point of 24°C. It has a density of 2.14 g/cm3 and is characterized by its toxicity and corrosive nature, which can cause severe irritation to the skin and eyes. Phosphorus trioxide is primarily used in the production of other chemicals.
Uses
Used in Chemical Industry:
Phosphorus trioxide is used as a precursor for the production of various chemicals, such as phosphoric acid, phosphates, and other phosphorus-containing compounds. Its ability to react with different substances makes it a versatile building block in the chemical industry.
Used in Agriculture:
In the agricultural sector, phosphorus trioxide is used as a component in the production of fertilizers. It provides essential phosphorus, which is a vital nutrient for plant growth and development.
Used in Water Treatment:
Phosphorus trioxide is employed in water treatment processes as a coagulant. It helps in the removal of suspended particles and impurities from water, making it suitable for various applications, including drinking water and industrial water supply.
Used in Metal Processing:
In the metal processing industry, phosphorus trioxide is used as a component in the production of certain metal phosphides. These compounds have applications in the electronics industry, such as in the manufacturing of semiconductors and other electronic components.
Used in Research and Development:
Due to its unique chemical properties, phosphorus trioxide is also utilized in research and development for the synthesis of new compounds and materials with potential applications in various fields, including pharmaceuticals, materials science, and energy storage.
Air & Water Reactions
Fumes in air. Reacts slowly with cold water to give phosphorous acid. Reacts vigorously with hot water to generate red phosphorus, phosphine (highly toxic and flammable) and phosphoric acid [Merck 11th ed. 1989].
Reactivity Profile
Phosphorus trioxide reacts exothermically with bases. Melted Phosphorus trioxide readily ignites in air. Instantly ignites with a flame of almost blinding brilliance when thrown into oxygen at 50-60°C [J. Am. Chem. Soc. 125:347. 1924]. Incompatible with ammonia, disulfur dichloride, halogens, oxygen, phosphorus pentachloride, sulfur, sulfuric acid, water [Bretherick, 5th ed., 1995, p. 1778].
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
Check Digit Verification of cas no
The CAS Registry Mumber 1314-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1314-24:
(6*1)+(5*3)+(4*1)+(3*4)+(2*2)+(1*4)=45
45 % 10 = 5
So 1314-24-5 is a valid CAS Registry Number.

A simple and green approach for preparation of ZnO2 and ZnO under sunlight irradiation

, p. 342 - 346 (2008/09/20)
A green approach is developed for sol-gel synthesis of ZnO and ZnO2 through photochemical reaction under sunlight irradiation. The component and structure of the sol and powders are systematically analyzed, and the reaction equations are deduced and the fabrication mechanisms are discussed. It is found that the ZnO2 powder is obtained when sintering temperature is below 200 °C, while ZnO powder is obtained as sintering temperature increases from 200 to 800 °C. All ZnO and ZnO2 prepared by this method are with crystal structure and high purity. Our fabrication process has low energy consumption and it brings no environment pollution. This simple and green approach is considered of great potential applications in industry.
