Mixed aromatics is an important raw material for chemical production, which is widely used in various fields. This paper will detail the properties and uses of mixed aromatics.

1. the properties of mixed aromatic hydrocarbons

mixed aromatic hydrocarbons refer to compounds composed of a mixture of two or more aromatic hydrocarbons. Common mixed aromatic hydrocarbons include benzene, toluene, xylene, etc. Mixed aromatics have many important physical and chemical properties, which make them widely used in chemical production.

1. Physical properties

mixed aromatic hydrocarbons are usually colorless and transparent liquids with special odors. Their boiling point and density increase as the number of carbon atoms increases. In addition, mixed aromatic hydrocarbons have good solubility and volatility, can dissolve many organic compounds, and are also easy to volatilize.

2. Chemical properties

mixed aromatics have typical aromaticity, and many typical aromatic reactions can occur, such as substitution reactions, addition reactions, oxidation reactions, etc. In addition, the mixed aromatics also have good stability and oxidation resistance.

2. the use of mixed aromatic hydrocarbons

mixed aromatic hydrocarbons have a wide range of applications in chemical production. The main uses include the following aspects:

1. Solvent

mixed aromatic hydrocarbons can be used as solvents to dissolve many organic compounds. They have good solubility and volatility and can be used in the manufacture of coatings, inks, adhesives, etc.

2. Production of synthetic rubber

mixed aromatics can be used as raw materials for the production of synthetic rubber, used in the manufacture of styrene butadiene rubber, butadiene rubber, etc. These synthetic rubbers are widely used in rubber products such as tires, hoses, and tapes.

3. Production of plastic

mixed aromatics can also be used as raw materials for the production of plastics for the manufacture of styrene, polystyrene and other plastic products. These plastic products have excellent heat resistance, corrosion resistance, insulation and other properties, widely used in various fields.

4. Production of chemical fiber

mixed aromatics can also be used as raw materials for the production of chemical fiber, used in the manufacture of polyester, acrylic and other chemical fiber products. These chemical fiber products have excellent elasticity, wear resistance, wrinkle resistance and other properties, and are widely used in clothing, home textiles and other fields.

In conclusion, mixed aromatics, as an important raw material for chemical production, has been widely used in various fields.
