Ntchito:

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. Kuphatikiza apo, phthalic nonhydride ndi cholowa chokonzekera mahomoni osiyanasiyana monga Auxin, omwe ndi ofunikira kwambiri pakulimbikitsa kukula kwa mbewu ndikukolola zokolola.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Monga chapakati pa utoto ndi zonunkhira, mafomu, zonunkhira, zonunkhira za utoto, zina zopangidwa ndi mankhwalawa zimapangitsa kuti zikhale zosatheka m'miyoyo ya anthu.

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. Mankhwala awa a polymer amakhala ndi zinthu zabwino kwambiri komanso kukhazikika kwamankhwala, ndipo amagwiritsidwa ntchito kwambiri pamagalimoto, zamagetsi, zomanga ndi magawo ena, ndikuthandizirani pakukula kwa gulu lamakono.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Itha kugwiritsidwa ntchito pa carbonulation, ma propylen okidation, kukonza kwa mpweya wa kaboni, aldehyde ndi ketone esterication, nitric acid ndi ma okosi a alkalination. Mu avorganian synthesis, phthalic tentydride amatha kugwiritsidwa ntchito polowetsa mchere wamtundu wa ammonium, ndipo amathanso kugwiritsidwa ntchito ngati wothandizira wothandizira polymes ya copper a sulfis. 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. Itha kugwiritsidwa ntchito ngati mitundu yosiyanasiyana yopatukana ndi catalytic, ndipo imathanso kugwiritsidwa ntchito pokonzekera ndikufalitsa ukadaulo wa mitundu yosiyanasiyana yazomwezo. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Kuphatikiza apo, FTHAIC Fhydride ikhoza kugwiritsidwanso ntchito ngati zopangira zophera tizilombo komanso mankhwala ophera tizilombo, kusewera gawo lofunikira pakuwonetsetsa kuti mbewu ndi zokolola.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Chifukwa cha madzi ake owira ndi kusinthika kwamphamvu, phthalica tebulo la phthalica limagwiritsidwa ntchito kwambiri ku mafuta oyenga ndi ma petrochemical ngati chinthu chosweka. Nthawi yomweyo, itha kugwiritsidwanso ntchito ngati chromatographic yoyeserera ndikupanga zonunkhira, etc., kupereka njira zothandizira kusanthula kwa mankhwala ndi kutulutsa kwa spice.

Kuphatikiza apo, FTHAIC Fhydride ikhoza kugwiritsidwanso ntchito kukonza sivallin, kudziwa shuga wa mkodzo, konzekeraninso ma synerginy, ndi njira yabwino kwambiri yopangira chitsulo. Mu mphira ndi pulasitiki, kupanga tepi a phthalica kungagwiritsidwe ntchito ngati zowonjezera za mphira komanso zowonjezera pulasitiki kuti musinthe magwiridwe antchito ndi mtundu.
