Phthalic Anhydride 99%, Ready For Shipment~

Application:

First, phthalic anhydride plays an important role in the field of drug manufacturing. It is a key raw material for the manufacture of anti-inflammatory drugs, gastrointestinal drugs, antibiotics, anticancer drugs and other drugs. In addition, phthalic anhydride is also a precursor for the preparation of various plant hormones such as growth hormone and auxin, which is of great significance for promoting plant growth and increasing crop yields.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. As an intermediate for dyes and spices, phthalic anhydride is used to make spices, pigments, synthetic fiber dyes, etc. Its unique chemical properties make it irreplaceable in these fields, adding rich colors and fragrances to people's lives.

In addition, phthalic anhydride also plays an important role in the manufacture of plastics and rubber. It is an important raw material for the manufacture of polymer compounds such as polyphenylene ether, polyamide, and polyimide. These polymer compounds have excellent physical properties and chemical stability, and are widely used in automobiles, electronics, construction and other fields, providing strong support for the development of modern society.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. It can be used for carbonylation, propylene oxidation, preparation of activated carbon esters, dry hydrogenation, aldehyde and ketone esterification, nitric acid and alkaline oxidation. In inorganic synthesis, phthalic anhydride can be used to synthesize ammonium salts, and can also be used as the main polymerization agent for the synthesis of copper zinc sulfide. These synthetic reactions provide a rich material basis for the development of the chemical industry.

In addition, phthalic anhydride also has important applications in the field of fine chemicals. It can be used for a variety of separation crystallization and catalytic reactions, and can also be used for the preparation and dispersion technology of various inorganic calcium sulfur polymers. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. In addition, phthalic anhydride can also be used as a raw material for insecticides and pesticides, playing an important role in ensuring the growth of crops and increasing yields.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Due to its low boiling point and high solubility, phthalic anhydride is widely used in petroleum refining and petrochemical industries as a cracking raw material. At the same time, it can also be used as a chromatographic analysis reagent and an extractant for spices, etc., providing an effective means for chemical analysis and spice extraction.

In addition, phthalic anhydride can also be used to prepare vanillin, determine urine sugar, prepare a variety of synergists and antifreeze, etc. It is also one of the raw materials for making polyvinyl chloride stabilizers and a good choice for metal surface treatment. In rubber and plastic manufacturing, phthalic anhydride can be used as a rubber additive and plastic additive to improve product performance and quality.
