Nadic Anhydride (NA) Phthalic Anhydride and Tetrahydrophthalic Anhydride price

Phthalic anhydride is an organic compound, molecular formula C8H4O3, is a cyclic anhydride formed by intramolecular dehydration of phthalic acid. Phthalic anhydride, a white solid, is an important raw material in chemical industry, especially used in plasticizer manufacturing.

Phthalic anhydride is a cyclic acid anhydride formed by the intramolecular dehydration of phthalic acid. It is used as an important raw material in the chemical industry, mainly for the production of plasticizers, alkyd resins, dyes, unsaturated resins, as well as certain medicines and pesticides. In addition, phthalic anhydride is also used in the synthesis of high-grade inks, artificial leather, synthetic rubber, insulating materials, etc

Phthalic anhydride has a wide range of applications. The following are some of the main application fields of phthalic anhydride:

Plasticizers: Phthalic anhydride is mainly used in the production of phthalate ester plasticizers (mainly dibutyl phthalate and dioctyl phthalate), which are widely applied in plastics, coatings, synthetic materials and other fields.

Resin: Phthalic anhydride is an important raw material for the production of unsaturated polyester resins and alkyd resins, which are widely used in coatings, adhesives and composite materials.

Dyes and fragrances: Phthalic anhydride is also widely used in the dye and fragrance industry. As an intermediate for dyes and fragrances, phthalic anhydride is used in the manufacture of fragrances, pigments, synthetic fiber dyes, etc.

Plastics and rubber: Phthalic anhydride is an important raw material for manufacturing high-molecular compounds such as polyphenylene ether, polyamide, and polyimide. These polymer compounds possess excellent physical properties and chemical stability, and are widely used in fields such as automobiles, electronics, and construction.

Medicine: Phthalic anhydride holds an important position in the field of drug manufacturing. It is a key raw material for manufacturing various drugs such as anti-inflammatory drugs, gastrointestinal drugs, antibiotics and anti-cancer drugs. In addition, phthalic anhydride is also a precursor for the preparation of various plant hormones such as growth hormones and auxin, which is of great significance for promoting plant growth and increasing crop yields.

Other applications: Phthalic anhydride is also used in the preparation of high-grade inks, artificial leather, synthetic rubber, insulating materials, etc. In the field of organic synthesis, phthalic anhydride has a wide range of applications and can be used in reactions such as carbonylation, propylene oxidation, and the preparation of activated carbon esters. In inorganic synthesis, phthalic anhydride can be used to synthesize ammonium salts and also serves as the main polymerizing agent for the synthesis of copper-zinc sulfides.

The above are the main application fields of phthalic anhydride. It should be noted that harmful substances may be produced during the production and use of phthalic anhydride. Therefore, corresponding safety measures need to be taken during operation.
