[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods of tert-butyl phenol, 2-tert-butyl phenol

Properties of tert-butylphenol

tert-butylphenol (Tert-Butylphenol, TBP) is an aromatic organic compound with the chemical formula C10H14O and a molecular weight of 150.22g/mol. Its structure is characterized by the attachment of a tert-butyl group (-C(CH3)3) and a hydroxyl group (-OH) on the benzene ring. Due to the presence of hydroxyl and tert-butyl, tert-butyl phenol has unique physical and chemical properties. It is usually colorless to light yellow solid or liquid, with high boiling point and melting point, low water solubility, but soluble in organic solvents such as ethanol, ether and benzene. Tert-butylphenol also has strong oxidation resistance and stability, and can maintain chemical stability under high temperature and acid-base environment.

Use of tert-butyl phenol

tert-butyl phenol is widely used in many industries, including:

1. plastics and rubber industry tert-butyl phenol is often used as an antioxidant and stabilizer to extend the service life of plastic and rubber products. It can effectively prevent the material from degrading due to heat, light or oxidation during processing and use.

2. Coatings and paints in the coating industry, tert-butyl phenol is used as an important intermediate for the synthesis of various resins and coating additives to improve the corrosion resistance and weather resistance of coatings.

3. lubricating oil additive: Tert-butyl phenol is also used in lubricating oil additives to enhance the oxidation resistance of lubricating oil and reduce the wear of engines and mechanical equipment.

4. Medicine and Pesticide in the pharmaceutical and pesticide industries, tert-butylphenol, as an important intermediate for the synthesis of drugs and pesticide active ingredients, has antibacterial, insecticidal and other functions.

Upstream and downstream raw materials of tert-butyl phenol

the production and application of tert-butyl phenol involves a series of upstream and downstream raw materials and processes.

Upstream raw materials:

1. isobutylene: Isobutene is one of the key raw materials for the production of tert-butyl phenol, which is produced by acid-catalyzed alkylation reaction.
2. Phenol phenol, as another main raw material, reacts with isobutylene to produce tert-butylphenol.

Downstream Products:

1. antioxidant tert-butyl phenol can be further processed to produce a variety of antioxidants, such as 2,6-di-tert-butyl-p-cresol (BHT), which is widely used in food, cosmetics and plastic products.
2. Resin: Tert-butyl phenol reacts with formaldehyde to form phenolic resin, which is widely used in coatings, adhesives and electronic materials.

Production process of tert-butyl phenol

the production of tert-butylphenol is mainly achieved by acid-catalyzed alkylation reactions. The typical process flow is as follows:

1. raw material preparation: Mix isobutylene and phenol in a certain ratio.
2. catalytic reaction in the presence of an acidic catalyst (such as sulfuric acid or solid acid catalyst), the alkylation reaction produces tert-butyl phenol.
3. separation and purification the tert-butyl phenol in the reaction product is purified by distillation or other separation methods.
4. Post-processing: Post-processing and quality inspection of products to ensure compliance with industrial application standards.

Storage method of tert-butyl phenol

because tert-butylphenol has certain chemical activity and volatility, its storage needs to pay attention to the following aspects:

1. temperature control: Should be stored in a cool, dry, well-ventilated environment, avoid direct sunlight and high temperature.
2. Container Selection: Use a well-sealed container for storage to prevent volatilization and oxidation. It is recommended to use stainless steel or glass containers to avoid chemical reactions.
3. Fireproof and explosion-proof: Because tert-butylphenol is flammable, it should be kept away from fire sources and high temperature objects. The storage area shall be equipped with fire prevention facilities and fire extinguishing equipment.
4. Moisture-proof measures: Avoid contact with water to prevent moisture absorption and deterioration of the product.

Environmental Protection and Safety

in the production and use of tert-butylphenol, attention must be paid to environmental protection and safety management. The production process should minimize the discharge of waste gas, waste water and solid waste to ensure compliance with environmental regulations. Operators should be equipped with appropriate protective equipment, such as protective gloves, glasses and face masks, to prevent chemical damage to human body.

market prospect

with the acceleration of industrialization and the continuous emergence of new materials and technologies, the market demand for tert-butylphenol has shown a steady growth trend. Especially in the fields of plastics, rubber, coatings and medicine, with the expansion of application scope and technological progress, the market prospect of tert-butyl phenol is broad. Market competition is also increasingly fierce, enterprises need to continuously improve the level of technology and product quality to meet customer needs and enhance market competitiveness.

Conclusion
