Read： 1129 Time：13months ago Source：Transform the World with Simplicity

White phosphorus is a non-metallic element with the chemical symbol P, which is a common raw material for chemical production. White phosphorus is a white or light yellow waxy solid at room temperature with a strong pungent odor. White phosphorus is lively in nature and is easy to react with oxygen, halogen and other elements, so it needs special attention during storage and use. This article will detail the properties and uses of white phosphorus.

1. White Phosphorus Properties

1. Physical Properties

White Phosphorus at room temperature is solid, soft, highly toxic. The melting point of white phosphorus is low, only 44.1 ℃, so it is easy to melt. White phosphorus is insoluble in water, but can be dissolved in organic solvents such as carbon disulfide.

2. chemical properties

the chemical properties of white phosphorus is very lively, easy to react with oxygen, halogen and other elements. White phosphorus can spontaneously ignite in the air to form phosphorus pentoxide, so it needs special attention during storage and use. White phosphorus can also react with halogens, metals, etc. to generate corresponding compounds.

2. the use of white phosphorus

white phosphorus as an important chemical raw material, widely used in various fields. The following are the main uses of white phosphorus:

1. preparation of phosphoric acid and its salts

white phosphorus can be used for the preparation of phosphoric acid and its salts, such as sodium dihydrogen phosphate, calcium hydrogen phosphate and so on. These compounds are widely used in the fields of food additives, detergents, pharmaceuticals and the like.

2. preparation of pesticides

of white phosphorus can be used for the preparation of organophosphorus pesticides, such as trichlorfon, dimethoate and so on. These pesticides play an important role in the control of agricultural pests and diseases.

3. preparation of incendiary bomb

white phosphorus ignition point is low, combustion can produce a lot of heat and smoke, it can be used for the preparation of incendiary bomb. In the military, incendiary bombs are often used to attack enemy targets and fortifications.

4. Preparation of Semiconductor Materials

White phosphorus can be used to prepare semiconductor materials, such as gallium phosphide, indium phosphide, etc. These materials have a wide range of applications in the electronics industry.

In short, white phosphorus, as an important chemical raw material, has a wide range of applications in various fields. In the process of use, it is necessary to pay attention to the toxicity and liveliness of white phosphorus, strictly abide by relevant regulations and safe operation procedures, and ensure the safety and reliability of the production and use process.
