Maombi:

Kwanza, anhydride ya phthalic inachukua jukumu muhimu katika uwanja wa utengenezaji wa dawa za kulevya. Ni malighafi muhimu kwa utengenezaji wa dawa za kuzuia uchochezi, dawa za utumbo, dawa za kukinga, dawa za anticancer na dawa zingine. 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.

Pili, anhydride ya phthalic pia hutumiwa sana katika tasnia ya nguo na harufu. 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.

Kwa kuongezea, anhydride ya phthalic pia ina jukumu muhimu katika utengenezaji wa plastiki na mpira. Ni malighafi muhimu kwa utengenezaji wa misombo ya polymer kama vile polyphenylene ether, polyamide, na 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.

Katika uwanja wa muundo wa kikaboni, anhydride ya phthalic ina matumizi anuwai. 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. Athari hizi za syntetisk hutoa msingi mzuri wa nyenzo kwa maendeleo ya tasnia ya kemikali.

Kwa kuongezea, anhydride ya phthalic pia ina matumizi muhimu katika uwanja wa kemikali nzuri. 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. Katika usindikaji wa madini, anhydride ya phthalic inaweza kutumika kwa usindikaji wa madini ya amana za ore ili kuboresha ufanisi wa madini na ubora wa 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.

Katika uzalishaji wa viwandani, anhidridi ya phthalic hutumiwa sana kama kutengenezea na kutolewa. 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.
