Phosphorus oxide (P2O3)(1314-24-5)
Phosphorus oxides, also known as trioxygen diphosphorus (P2O3), have the chemical substance registry number (CAS number) of 1314-24-5 and are an important oxide in the field of inorganic chemistry. In addition, it has other aliases, such as diphosphorus trioxide and trioxygen diphosphorus. The chemical formula of phosphorus oxide can be simply expressed as O.P, and it is a white crystalline solid or liquid with a melting point of 24°C and a relatively high density of 2.14 g/cm³. Phosphorus oxide has certain application value in industrial production, such as being used as a flame retardant for plastics and rubber, and a preservative for wood. However, it is a toxic and highly corrosive chemical substance. If the body comes into direct contact with this substance, it may cause serious irritation to the skin and eyes, and even may cause serious health problems. Therefore, when using phosphorus oxide, we must be highly vigilant and take appropriate safety measures such as wearing protective clothing and gloves. At the same time, the storage and transportation of phosphorus oxide also need to be strictly regulated according to relevant regulations to prevent accidents.
