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. Eia kekahi,ʻo ka phthacal anyddride he mea nui no ka hoʻomākaukauʻana i nā pue kanu a me ka hoʻonuiʻana i nā hua kanu.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. E like me kahi kikowaena waena no nā papa a me nā spies, e hana anaʻo phthac i nā mea kanu pono, e hoʻohui i nā mea momona.

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. ʻO kēia mau polymer i loaʻa i nā pili kino maikaʻi loa a me ka paʻaʻana o ka maʻi, a ua hoʻohanaʻia i nā kaʻa, e nāʻenehana ikaika, e hāʻawi ana i nā mea kōkua ikaika no ke kūkuluʻana i nā kaiāulu hou.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Hiki ke lilo i mea kālepa ke kaʻa, ka maʻi proypony, e hoʻomākaukau ana i nā edana hoʻomohala, hoʻomaloʻoʻana a me ka maʻi alkaline Ma ke kāweleʻana i loko o ka synthesis synthesic, hiki ke hoʻohanaʻo Phthalic Anyddride i ka syntheszene i nā salpside kumukūʻaiʻo Zincumside nui loa. 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. Hiki ke hoʻohanaʻia no nāʻano hoʻohewaʻana e hoʻokaʻawale ai a me nā maʻi catalikate, a e hiki nō i kaʻenehanaʻoihana o ka hoʻomākaukauʻana. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Eia kekahi, hiki ke hoʻohanaʻiaʻo Phthalic Anyddride e like me ka mea i loko o nā mea i hoʻopiliʻia a me nā pesticides, e pāʻani ana i ka ulu nui.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Ma muli o kona wahi haʻahaʻa haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe,ʻo phthalic Anydride i hoʻohanaʻia i kaʻoihana petrolem e like me keʻano o keʻano o keʻano. I ka manawa like, hiki iā ia ke hoʻohanaʻia e like me kahi loiloi chromatographic a me kahi mea hou aku no nā meaʻala, etc.

Eia kekahi, hiki ke hoʻohana pūʻiaʻo PhThalic Anyddride e hoʻomākaukau i ka Vanillin, e koho i nāʻano kīwila no ka hanaʻana i ka hanaʻoka. I loko o ka'ōpala a me ka hana pānaʻi, hiki ke hoʻohanaʻiaʻo phthalic Anydride e like me ka hoʻohuiʻana a me ka hoʻohuiʻana o ka huahana a me ka maikaʻi.
