The nature and use
of petroleum ether in the field of chemical production raw materials
1. Introduction

Petroleum ether is a widely used chemical raw material, mainly derived from the fractionation process of petroleum. Because of its unique physical and chemical properties, petroleum ether has a wide range of applications in the field of chemical production raw materials. In this paper, the properties and uses of petroleum ether will be discussed in detail.

2. the nature of petroleum ether

1. physical properties: petroleum ether is a colorless and transparent liquid, with a faint taste of oil and gas. Its density is smaller than water, insoluble in water, but can be miscible with many organic solvents. Petroleum ether has a wide range of boiling points, usually according to its different boiling points, can be divided into 30-60 ℃, 60-90 ℃, 90-120 ℃ and other different specifications.
2. Chemical properties: Petroleum ether has good stability and is not prone to chemical reactions, but it can burn. The main components of petroleum ether are hydrocarbons, in which the carbon chain length is generally between C5-C16 and.

3. the use of petroleum ether

petroleum ether in the field of chemical production of raw materials has a wide range of uses, the following is its main application areas:

1. cleaning agent: because petroleum ether has good solubility and low toxicity, it is often used as a cleaning agent, used to remove metal, plastic and other surface grease, stains and so on.
2. Solvent: Petroleum ether can be used as a solvent for many compounds, such as resin, paint, rubber, etc. Because of its low boiling point and easy volatilization, it is often used to prepare some chemicals that require low boiling point solvents.
3. Extractant: Petroleum ether can be used to extract some organic substances, such as vegetable oils, animal fats, etc., as well as products in some chemical reactions.
4. Dewaxing agent: Petroleum ether can be used to remove wax from petroleum and improve the fluidity of petroleum.

4. conclusion

petroleum ether as an important chemical raw material, has a wide range of applications in the field of chemical production raw materials. Due to its unique physical and chemical properties, petroleum ether plays an important role in the field of cleaning agents, solvents, extractants and dewaxing agents. However, although petroleum ether is widely used, it is also necessary to pay attention to safety during use to avoid risks such as fire and poisoning. At the same time, the waste petroleum ether also needs to be properly treated to avoid harm to the environment and human health.

in the future, with the progress of science and technology and the improvement of environmental protection requirements, the application field of petroleum ether may change, but its important position in the field of chemical production raw materials will not change. Therefore, we need to continue to study the properties and uses of petroleum ether in order to improve its utilization efficiency and safety, and make greater contributions to the development of the chemical industry.
