Crude phenol has an important position in the field of chemical production raw materials, and its upstream and downstream related products are widely used. This article will detail the upstream and downstream associated products of crude phenol, including upstream raw materials and downstream products.
1. upstream raw material
1. Coal tar
Coal tar is the main raw material for the production of crude phenol, accounting for about 70% of the raw material for the production of crude phenol. Coal tar is a dark brown viscous liquid produced in the process of coal dry distillation, which is rich in aromatic hydrocarbon compounds, such as benzene, toluene, xylene and so on. By distillation separation, phenolic compounds with different boiling points, including crude phenol, can be obtained.
2. Petroleum fraction
Petroleum fraction is also one of the raw materials for the production of crude phenol, mainly derived from reformate and pyrolysis oil in the process of petroleum processing. These fractions contain a large amount of aromatic compounds, which can be separated and purified to obtain crude phenol.
2. Downstream Products
1. Phenol
Phenol is one of the important downstream products of crude phenol and has a wide range of uses. Phenol is mainly used in the production of phenolic resin, bisphenol A, caprolactam and other chemicals, but also can be used in pharmaceutical, pesticide, dye and other fields.
2. Cresol
Cresol is another important downstream product of crude phenol, including three isomers of o-cresol, m-cresol and p-cresol. Cresol is mainly used in the production of pesticides, fungicides, preservatives and other pesticides, but also for the manufacture of dyes, spices and so on.
3. Nitrophenol
Nitrophenol is one of the downstream products of crude phenol, which has the functions of sterilization and corrosion prevention. Nitrophenol can be used in the manufacture of pesticides, pharmaceuticals, dyes, etc.
4. Alkylphenol
Alkylphenol is one of the downstream products of crude phenol. It has good oxidation resistance and thermal stability and can be used to produce antioxidants, lubricating oil additives, etc.
In short, crude phenol plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive. By understanding the upstream and downstream related products of crude phenol, we can better understand the status and role of crude phenol in the chemical industry chain, and provide ideas for the development and application of new chemical products.
