Read： 1109 Time：14months ago Source：Transform the World with Simplicity

Propane is a common chemical raw material with many important properties and uses. This article will detail the nature of propane, production methods, safety and use of knowledge.

1. the nature of propane

propane is a colorless, odorless, flammable gas with the molecular formula C3H8. It has the following properties:

1. Physical properties: The boiling point of propane is -42.1 ℃, the melting point is -187.7 ℃, the density is larger than air, and it is slightly soluble in water.
2. Chemical properties: Propane has high chemical stability, but at high temperature and in the presence of catalyst, cracking, oxidation, halogenation and other reactions can occur.

2. propane production methods

propane can be produced by the following methods:

1. Natural gas separation: Separating propane from natural gas is a commonly used method in industrial production.
2. Petroleum cracking: A large amount of propane is produced in the process of petroleum cracking, and high-purity propane can be obtained through separation and purification.
3. Biomass gasification: By gasifying biomass waste, combustible gas containing propane can be generated, and propane can be obtained by further separation and purification.

3. the safety
of propane
Although propane is a flammable gas, it can ensure its safety if used under suitable conditions. The following are some precautions for the safe use of propane:

1. Storage: Propane should be stored in a cool, ventilated and dry place, away from fire and heat sources.
2. Transportation: Special transportation vehicles should be used when transporting propane, and relevant regulations and standards should be observed to ensure transportation safety.
3. use: the use of propane should comply with the relevant safety procedures, to ensure the use of safety.

4. the use of propane

propane in the field of chemical production has a wide range of uses, the following are its main uses:

1. fuel: propane can be used as fuel for combustion to generate heat and electricity.
2. Chemical raw materials: Propane can be used as chemical raw materials for the production of propylene, propanol, acetone and other important organic chemicals.
3. Refrigerant: Propane can be used as a refrigerant, especially in the field of low-temperature refrigeration.
4. Solvents: Propane can be used as a solvent for the extraction and separation of certain substances.

In conclusion, propane, as a common raw material for chemical production, has a wide range of uses and important value. In the process of use, should abide by the relevant safety operation procedures and regulations and standards, to ensure the safety of use.
