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. Na mgbakwunye, Phhalic Anhalic bụkwa ihe dị mkpa maka nkwadebe nke homonụ osisi dị iche iche dị ka homonụ na auxin, nke dị oke mkpa maka ịkwalite ihe ọkụkụ.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Dịka onye etiti na ngwa nri, a na-ejikarị phyalic a na-eme ihe eji eme nri, ụcha fiber, wdg.

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. Cooks ndị a nwere ihe dị mma na-ahụ maka kemịkalụ, ma na-ejikwa ụgbọ mmiri, ma na-eji ọtụtụ ebe, eletriki, owuwu na mpaghara ndị ọzọ, na-enye nkwado siri ike maka mmepe nke mmepe nke mmepe nke oge a.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Enwere ike iji ya maka carbonylation, proplene oxidation, nkwadebe nke ụlọ carbon, hydrogen, Aldehyde na Empene oxidation. Na njikọta, Phhalic Anyhedide nwere ike iji synesize ammonium nnu, ma nwee ike iji ya dị ka onye isi polymerization maka njikọta nke ọla kọpa na-agba minc sulcide. 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. Enwere ike iji ya maka iche iche nkewa na mmeghachi omume nkewapụ, ma enwere ike iji ya maka nkwadebe ma gbasaa nke polymer sọlfọ dị iche iche. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Na mgbakwunye, Phhalic Anhydride dị ka akụrụngwa maka ọgwụ na ọgwụ ọgwụ, na-arụ ọrụ dị mkpa iji hụ uto nke ihe ọkụkụ na ihe ọkụkụ.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. N'ihi oke mmiri dị ala ya, a na-eji Phhalic Anhalic Ashydride na-ejikarị ya na kọmpụta anụ ụlọ na ụlọ ọrụ petrolem dị ka ihe na-agbada. N'otu oge ahụ, enwere ike iji ya dị ka nyocha chromatographic na onye na-ewepụta maka ngwa nri, wdg, na-enye ụzọ dị irè maka nyocha kemịkalụ na mmịmịghe.

Na mgbakwunye, Phhalic Anhydride iji kwadebe vanillin, na-ekpebi shuga dị iche iche na antifrrezes na-eme ka ọ dị mma polyvinyl chloride chloride chloride ọgwụgwọ. Enwere ike iji ya roba na mkpoputa rọba, phyalic anythic dị ka ihe mgbakwunye roba na plastinitive na-agbanwe iji meziwanye arụmọrụ ngwaahịa na ogo.
