Technical parameters and specifications of phenol

Technical parameters and specifications of phenol

phenol is an important organic compound, which is widely used in the fields of chemical industry, material science, pharmacy and pesticide. Its chemical and physical properties make it an irreplaceable role in many industries. This article will analyze the technical parameters and specifications of phenol in detail to help you better understand the characteristics and applications of this compound.

1. Introduction of phenol

phenol, chemical formula C6H5OH, is a colorless crystal or white solid with a special smell. It is solid at room temperature with a melting point of 40.8°C and a boiling point of 181.7°C. Phenol is a weak acid that can react with strong bases to form salts. Its chemical properties make it widely used in many fields.

2. Technical parameters of phenol

in the selection and use of phenol, it is essential to know its technical parameters. The following are the main technical parameters of phenol:

• appearance colorless crystals or white solids, odorless or slightly peculiar odor.
• Melting Point: 40.8°C
• boiling Point: 181.7°C
• density:1.0718 g/cm³
• pH weakly acidic, pKa about 10
• solubility slightly soluble in water, but miscible with organic solvents such as ethanol and ether.
• Toxicity: Has a certain toxicity, irritation to the eyes and skin.

These technical parameters determine the suitability of phenol for different applications. For example, in the manufacture of phenolic resins, the melting and boiling points of phenol are important considerations, while its miscibility with organic solvents affects its application in coatings and plastics.

3. Specification of phenol

the specifications of phenol vary mainly according to its purity and use. The following is a detailed description of several common specifications:

• industrial grade phenol: Purity is usually above 95%, suitable for large-scale industrial production. This specification of phenol is mainly used in the manufacture of phenolic resins, plasticizers and pesticides.
• food grade phenol: Higher purity, usually up to 99.9 percent, in line with food additive standards. It is mainly used as a preservative and antioxidant in the food industry.
• Pharmaceutical grade phenol: Purity requirements are highest, usually more than 99.99 percent, and certified to strict pharmaceutical standards. Phenols of this specification are used in pharmaceutical manufacturing and medical applications.

Choosing the appropriate specifications depends on the specific application. For example, food-grade phenol must meet higher hygiene and safety standards, while pharmaceutical-grade phenol is subject to strict quality inspection procedures.

4. Application areas of phenol

the application range of phenol is very wide, the following are its main application areas:

• plastics and resins phenol is the main raw material for the manufacture of phenolic resin, which is widely used in insulating materials, coatings and adhesives.
• Epoxy Resin: Phenol is combined with epoxy resin to manufacture high-performance composite materials.
• Pesticides and pharmaceuticals: Phenol and its derivatives have important applications in the pesticide and pharmaceutical industries, such as as fungicides and analgesics.
• Coatings and Plasticizers: Phenol is used to make plasticizers in coatings to improve the toughness and durability of coatings.

5. Quality control and storage of phenol

in order to ensure the quality and performance of phenol, strict quality control is required during production and use. The following are the quality control and storage considerations for phenol:

• quality Control quality control of phenol includes purity testing, impurity analysis and physical property testing. These steps ensure that the phenol meets industry standards.
• Storage: Phenol should be stored in a cool, well-ventilated place, away from fire sources and oxidants. Due to its flammability, storage conditions must comply with safety regulations.

6. Conclusion

phenol is an important organic compound, and its technical parameters and specifications directly affect its application effect and safety. By understanding its technical parameters and specifications, phenol can be better selected and used to ensure its efficient application in various fields. Whether in industrial production or pharmaceutical applications, the high quality and stability of phenol is the key to its success.
