The nature and use
of diesel aromatics
1. Introduction

diesel aromatics is an important part of the field of chemical production raw materials, and plays a key role in improving the quality and performance of diesel oil. This article will introduce the nature and use of diesel aromatics in detail, aiming to deepen the understanding and understanding of diesel aromatics.

2. Diesel Aromatics Properties

1. Physical Properties

Diesel Aromatics is a class of hydrocarbons with aromatic structure, mainly including benzene, toluene, xylene and so on. They generally have a higher boiling point, density and viscosity, and a lower vapor pressure and volatility.

2. Chemical properties

diesel aromatics have high chemical stability and thermal stability, and can maintain stability under high temperature and high pressure. In addition, they have good oxidation and corrosion resistance.

3. the use of diesel aromatics

1. Improve the quality of diesel

diesel aromatics can effectively improve the quality of diesel and improve its combustion performance. Adding appropriate amount of aromatics can reduce the freezing point of diesel oil, improve its fluidity, and make it can be used normally under low temperature conditions. In addition, aromatics can also increase the cetane number of diesel fuel, make it burn more completely, and reduce emission pollution.

2. Production of chemical raw materials

diesel aromatics can be used as an important source of chemical raw materials, such as benzene, toluene, xylene and so on. These compounds can be used in the production of plastics, rubber, fibers, dyes, fragrances and other products, widely used in various fields.
Precautions for
4.

When using diesel aromatics, you need to pay attention to the following:

1. Control the amount of addition: When adding aromatics, control the appropriate amount of addition to avoid excessive diesel quality.

2. Storage conditions: Aromatic hydrocarbons should be stored in a cool, dry, well-ventilated place, away from direct sunlight and high temperatures.

3. Operation safety: When operating aromatic hydrocarbons, pay attention to safety, avoid contact with skin and inhalation of its vapor.

5. conclusion

In conclusion, diesel aromatics plays an important role in the field of chemical production raw materials, which can improve the quality and performance of diesel oil and serve as a source of chemical raw materials. When using, it is necessary to pay attention to control the amount of addition, storage conditions and operational safety.
