Benzene is an important chemical raw material, widely used in organic synthesis, pharmaceutical, rubber, dyes and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of pure benzene are very rich. This article will introduce the main upstream and downstream related products of pure benzene. The upstream product of

1. pure benzene
the upstream feedstock of
pure benzene is mainly petroleum. After petroleum is processed by distillation, cracking and other processes, aromatic mixtures containing pure benzene can be obtained. By separating and purifying the aromatic hydrocarbon mixture, pure benzene with high purity can be obtained finally.

2. the downstream products of pure benzene

1. Styrene
Styrene is an important organic compound, mainly produced by the alkylation reaction of pure benzene and ethylene. Styrene is widely used in the production of plastics, rubber, synthetic fibers and other products, is an important raw material in the chemical industry.
2. Aniline
Aniline is an organic compound prepared from pure benzene and ammonia by addition reaction. Aniline is an important chemical intermediate, widely used in the production of dyes, drugs, rubber additives.
3. Benzoic Acid
Benzoic acid is an organic acid, which is prepared by oxidation of pure benzene. Benzoic acid and its derivatives are widely used in food, medicine, dyes and other fields.
4. Cyclohexane
Cyclohexane is an important organic solvent and chemical intermediate, which is used in the production of nylon, caprolactam and other products.

3. of pure benzene derivatives

In addition to the above-mentioned main upstream and downstream related products, pure benzene can also be produced through a series of chemical reactions to produce more derivative products, such as phenol, acetone, benzaldehyde and so on. These derivatives are widely used in medicine, pesticides, spices and other fields.

In short, pure benzene as an important chemical raw material, its upstream and downstream related products are very rich, widely used in many fields. With the continuous progress of science and technology and the continuous development of the chemical industry, the upstream and downstream related products of pure benzene will also continue to increase, providing more support for the development of various fields.
