Isicelo:

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. Ngaphezu kwalokho, i-phthalic anhydride ibuye ibe yisandu sokulungiswa kwama-hormone okutshala ahlukahlukene njengokukhula kwama-hormone kanye ne-auxin, okubaluleke kakhulu ekuthuthukiseni ukukhula kwezitshalo kanye nokwanda kwezitshalo.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Njengomphakathi we-Dyses kanye nezinongo, i-phthalic anhydride isetshenziselwa ukwenza izinongo, imibala, izakhiwo zayo zokwenziwa zamakhemikhali ziyenza ingafinyeleleki kule mikhakha, engeza izici ezicebile ezimpilweni zabantu.

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. Lawa makhompiyutha e-polymer anezinto ezinhle kakhulu zomzimba kanye nokuqina kwamakhemikhali, futhi asetshenziswa kabanzi ezimotweni, e-elektroniki, ekwakheni nakwezinye izinkambu, anikeze ukwesekwa okuqinile ekuthuthukiseni umphakathi wanamuhla.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Ingasetshenziselwa i-carbonylation, i-propelene oxidation, ukulungiswa kwe-activated carbon ecrers, i-hydrogenation eyomile, i-aldehyde ne-ketone yokuchazwa, i-nitric acid kanye ne-oxidation ye-alkali. Ngokuvumelanisa kwe-inorganic, i-anhydride ye-phthalic ingasetshenziswa ukuhlanganisa usawoti we-ammonium, futhi futhi ingasetshenziswa njenge-ejenti enkulu ye-polymerization yokuhlanganiswa kweCopper Ninc 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. Ingasetshenziselwa ukuhlukaniswa okuhlukahlukene okuhlukanisayo kanye nokusabela kwe-catalytic, futhi nakho kungasetshenziselwa ubuchwepheshe kanye nobuchwepheshe bokuhlakazeka kwama-polfure ahlukahlukene we-inOrganic calcium sulfor. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Ngaphezu kwalokho, i-phthalic anhydride nayo ingahle isetshenziswe njengento eluhlaza ye-insecticides kanye nezibulala-zinambuzane, idlala indima ebalulekile ekuqinisekiseni ukukhula kwezilimo kanye nezithelo ezandayo.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Ngenxa yephuzu layo elibilayo elisezingeni eliphansi ne-solubility ephezulu, i-phthalic anhydride isetshenziswa kabanzi ekucongeni kukaphethiloli kanye nezimboni ze-petrochemical njengezinto eziphikisayo eziqhekekile. Ngasikhathi sinye, futhi ingasetshenziswa njenge-Chromatographic ehlaziya i-realent kanye ne-extracting yezinongo, njll., Ukunikeza izindlela ezisebenzayo zokuhlaziywa kwamakhemikhali kanye nokukhishwa kwezinongo.

Ngaphezu kwalokho, i-phthalic anhydride nayo ingasetshenziswa ukulungiselela i-vanillin, inqume ushukela womchamo, lungiselela ahlukahlukene ama-synergists kanye no-antifreeze, futhi kungenye yezinto zokwenziwa kwe-polyviny chloride kanye nokwelashwa okuhle kwensimbi. E-Rubber ne-Plastic Anhydride, i-phthalic anhydride ingasetshenziswa njengesengezo senjoloba nepulasitiki sokwengeza ukusebenza komkhiqizo kanye nekhwalithi.
