[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of o-butyl phenol, is o-phenyl phenol toxic?

Properties of o-Butylphenol

Ortho-butylphenol (o-Butylphenol) is an organic compound with the chemical formula C10H14O. Its appearance is a colorless to light yellow liquid with a typical phenolic odor. Ortho-butylphenol has a melting point of -5°C, a boiling point of 238°C, and a density of 0.95g/cm³. It is volatile and corrosive. Its solubility in water is low, but it has good solubility in organic solvents such as ethanol, ether, acetone, etc.

Use of o-butyl phenol

O-butyl phenol is widely used in industry, mainly for synthetic resins, plasticizers, antioxidants, fungicides, etc. In the synthetic resin, o-butyl phenol is an important monomer of phenolic resin, which gives the resin good heat resistance and mechanical properties. As a plasticizer, it can improve the flexibility and processability of the polymer. O-butyl phenol is also an effective antioxidant, widely used in rubber, plastics, lubricants and other fields to prevent material aging. It is also a fungicide, used in agriculture, medicine and other fields.

Upstream raw material for o-butyl phenol

The production of o-butylphenol is mainly achieved by an alkylation reaction. Upstream feedstocks include phenol and butane. Phenol is produced by the oxidation of benzene, which is a common chemical raw material. Butane is obtained by cracking natural gas or petroleum. In the production process, phenol and butane are alkylated under the action of acidic catalyst to produce o-butyl phenol. The reaction requires strict control of reaction temperature and pressure to ensure high yield and high purity of the product.

o-Butylphenol downstream products

As an important intermediate, o-butylphenol is widely used in the production of downstream products. Its main downstream products include phenolic resins, plasticizers, antioxidants and biocides. Phenolic resin is widely used in coatings, adhesives, electronic packaging materials and other fields. Plasticizers are used in the production of plastic and rubber products to improve their flexibility and durability. Antioxidants are used to delay the aging process of materials and improve the service life of products. Fungicides are used in agriculture and medicine to prevent and control diseases.

O-Butyl Phenol Storage Method

Since o-butylphenol has a certain volatility and corrosiveness, its storage requires special attention. O-butyl phenol should be stored in a cool, ventilated warehouse, away from direct sunlight and high temperature environment. Storage containers shall be of corrosion resistant materials such as stainless steel or special plastics and shall be well sealed to prevent volatilization and leakage. Storage areas should be kept away from ignition and heat sources and well ventilated. Operators should wear appropriate protective equipment such as gloves, goggles and protective clothing to avoid direct contact with o-butylphenol.

Safety and Environmental Considerations

When handling and using o-butylphenol, it is necessary to comply with relevant safety and environmental regulations. O-Butylphenol is irritating to the skin, eyes and respiratory tract and may cause burns or allergic reactions after exposure. Prolonged exposure to high concentrations of o-butylphenol may have adverse health effects. Therefore, operators should take appropriate personal protective measures to avoid inhalation and skin contact.

For waste disposal of o-butylphenol, national and local environmental regulations should be followed. Discarded o-butylphenol and its containers shall be properly disposed to avoid environmental pollution. The waste liquid can be treated or incinerated by a professional chemical waste treatment company to ensure safety and environmental protection.

Market prospects and trends

As an important chemical intermediate, o-butylphenol has a stable market demand and a wide range of applications. With the advancement of industrialization and the development of new materials, the demand for o-butylphenol is expected to continue to grow. In the future, with the increasingly stringent environmental regulations, the production process and application fields of o-butylphenol will be further optimized and expanded. For example, the production of o-butylphenol through green chemistry to reduce the impact on the environment; the development of new application areas, such as high-performance materials and bio-based products, to increase their added value and market competitiveness.

Conclusion

O-butyl phenol is a widely used chemical intermediate, and its properties and uses determine its important position in industrial production. Understanding its upstream and downstream raw materials, storage methods and safety precautions is essential to ensure production safety and environmental protection. With the growth of market demand and technological progress, the application prospect of o-butylphenol will be broader. By continuously optimizing the production process and expanding the application field, o-butyl phenol will continue to play an important role in the development of related industries.
