The nature and use
of industrial naphthalene
1. introduction
industrial naphthalene is an important chemical production raw material, widely used in many fields. In this paper, the properties and uses of industrial naphthalene are discussed in detail in order to have a deeper understanding of it.
2. the nature of industrial naphthalene
industrial naphthalene is an organic compound, belonging to aromatic hydrocarbons, molecular formula C10H8. Pure naphthalene is colorless or white shiny flaky crystals with a special odor. Its melting point is 80.5 ℃, boiling point is 217.9 ℃, insoluble in water, but soluble in hot alcohol and ether and other organic solvents. Naphthalene has a vapor specific gravity of 3.96 and burns in air to produce a blue flame and a special smell. The chemical properties of
industrial naphthalene are relatively stable, and the addition reaction is not easy to occur, but the substitution reaction can be carried out under certain conditions. In addition, naphthalene also has good thermal stability and can be processed and treated at high temperatures.
3. industrial naphthalene use
1. preparation of dyes and pigments
industrial naphthalene can be used as raw materials for the preparation of a variety of dyes and pigments, such as phthalocyanine blue, permanent purple and so on. These dyes and pigments are widely used in plastics, rubber, ink, leather and other industries.
2. Production of pesticides
industrial naphthalene can be used to produce a variety of pesticides, such as pesticides, fungicides, etc. These pesticides play an important role in controlling crop diseases and insect pests and improving crop yields.
3. Manufacture of spices
industrial naphthalene can also be used as a raw material for the manufacture of spices, for the production of artificial musk and other spices. These spices are widely used in food additives, cosmetics and other fields.
4. Production of resins and plastic
industrial naphthalene can be used as raw materials for the production of a variety of resins and plastics, such as phenolic resin, naphthol formaldehyde resin. These resins and plastics have excellent properties and are widely used for electrical insulation, corrosion resistance, etc.
4. conclusion
industrial naphthalene as an important raw material for chemical production has a wide range of applications. Through the in-depth understanding of the nature and use of industrial naphthalene, we can better grasp its processing and application technology, and provide strong support for the development of the chemical industry.
