The nature and use
of coking phenol in the field of chemical production raw materials
1. Introduction

coking phenol is an important chemical raw material, widely used in plastics, synthetic fibers, pharmaceuticals, pesticides, spices and other fields. Coking phenol has unique properties and uses, which is of great significance for the production and development of chemical products. In this paper, the properties and uses of coking phenol are discussed in detail.

2. The properties of coking phenol

1. Physical properties

coking phenol is a colorless or yellowish crystalline solid with a special pungent odor. Its melting point is higher, usually between 40-42 ℃, boiling point is around 182 ℃. Coked phenol is insoluble in water, but soluble in ethanol, ether, acetone and other organic solvents.

2. chemical properties of

coking phenol chemical properties are more active, prone to substitution, oxidation, reduction and other reactions. The hydrogen atom on the phenolic hydroxyl group has a certain acidity and can react with alkali to form a salt. In addition, the coking phenol also has a strong reduction, can be oxidized to generate benzoquinone and other compounds.

3. the use of coking phenol

1. synthetic plastics and synthetic fiber

coking phenol can be used as a raw material for synthetic plastics and synthetic fibers. For example, it reacts with formaldehyde to produce phenolic resin, which is a plastic material with excellent heat resistance, electrical insulation resistance and corrosion resistance, and is widely used in electrical appliances, automobiles, construction and other fields. In addition, the coking phenol can also be used for the production of polyester, nylon and other synthetic fibers.

2. pharmaceutical and pesticide

of coking phenol in the field of medicine and pesticide is also widely used. For example, it can be used as a bactericide, preservative in the production of drugs and food. In addition, the derivatives of coking phenol can also be used to make pesticides such as pesticides and herbicides.

3. Perfume and Dye

Coked phenol can also be used to produce perfumes and dyes. For example, its derivatives can be used to make vanillin, vanillic acid and other spices, as well as some azo dyes and phthalocyanine dyes.

4. conclusion

coking phenol as an important chemical raw material, has a wide range of applications in plastics, synthetic fibers, pharmaceuticals, pesticides, spices and other fields. Its nature and use are of great significance to the production and development of chemical products. In the future, with the continuous development of science and technology, the application field of coking phenol will continue to expand.
