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. Hei taapiri, ko te phthail Anydride he mea nui ano hoki mo te whakarite i nga momo tipu tipu me te pakeke, he mea nui ki te whakatairanga i te tipu tipu me te whakapiki ake i nga hua tipu.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Hei takawaenga mo nga waikano me nga mea kakara, ka whakamahia te anydride hei taonga kakara, ko nga poaka, ko nga momo matū rereke, me te kakara o te ao.

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. Ko enei pūhui polymer he pai rawa te tinana me te pumau matū, me te whakamahi i nga motuka, te hanga me etahi atu mara, e tautoko ana i te whanaketanga o te hapori hou.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Ka taea te whakamahi mo te waro, ko te whakapiripiri propone, te whakarite i nga miihini waro whakahohe, te hydiotete maroke, te konutai me te ketone me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric me te waikawa nitric. I roto i te whakahiato i roto i te waihanga, phthail anydride ka taea te whakamahi i nga tote haukini, ka taea hoki te whakamahi hei kaihoko mo te polymerizatization mo te whakahiato o te konupora o te konupora o te konuporaa. 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. Ka taea te whakamahi mo te maha o nga tauwehenga wehenga me te catalytic, a ka taea hoki te whakamahi mo te hangarau whakarite me te hangarau o nga momo whanariki waro. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Hei taapiri, ka taea hoki te whakamahi i te phthail anydride hei rauemi mata mo nga pepeke me nga pesticides, e whai wāhi nui ana ki te whakarite i te tipu o te hua me te piki haere o nga hua.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Na te mea ko tana tino kohua me te whakaraeraetanga nui, ko te phthail Anydride e whakamahia whānuitia ana i te hinu hinu hinu me nga umanga petrochemical hei taonga whakairo. I te wa ano, ka taea hoki te whakamahi hei tātaritanga pouaka whakaata me te tangohanga mo nga mea kakara, me etahi atu, e whai hua ana mo te tātaritanga matū me te tangohanga Spice.

I tua atu, ka taea hoki te whakamahi i te antail anydride hei whakarite i a Vavillin, whakarite i te waikawa mine, he mea pai mo te mahi polyvinyl chloride. I roto i te Hangarau me te kirihou, ka taea te whakamahi i te phthail Anydride hei taapiri taapiri me te taapiri kirihou hei whakapai ake i nga mahi me te kounga.
