Binaphthol plays an important role in the field of raw materials for chemical production, and its upstream and downstream related products are extensive. The following is a detailed description of the upstream and downstream associated products of dinaphthol.

upstream products:

1. benzene: benzene is one of the main raw materials of two naphthol, through a series of chemical reactions, can be converted into two naphthol. The production methods of benzene mainly include catalytic reforming method, ethylene cracking method and coking by-product method.
2. Naphthalene: Naphthalene is another important raw material of two naphthol, which can be separated from coal tar. Naphthalene can also be produced by a catalytic dehydrogenation process.

downstream products:

1. Dyes: dinaphthol can be used to produce a variety of dyes, such as acid dyes, direct dyes, mordant dyes, etc. These dyes are widely used in textile, printing and dyeing, leather and other industries.
2. Plastic and rubber antioxidant: dinaphthol can be used as an antioxidant for plastics and rubber to improve its oxidation resistance and heat resistance and extend its service life.
3. Pesticides: The derivatives of two naphthol can be used as pesticides, with sterilization, insecticidal and other effects, widely used in agricultural production.
4. flavors and fragrances: two naphthol can be used to produce flavors and fragrances, giving products specific aroma and taste, and improving the sensory quality of products.

summary:

dinaphthol has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products involve dyes, plastics, rubber, pesticides, flavors and fragrances and other fields. With the continuous development of science and technology, the application field of two naphthol will be further expanded, which will play a greater role in the development of the chemical industry.
