Phthalic Anhydride 99%, Yokonzeka Kutumizidwa ~

Ntchito:

Choyamba, phthalic anhydride imagwira ntchito yofunika kwambiri popanga mankhwala. Ndi chinthu chofunikira kwambiri popanga mankhwala oletsa kutupa, mankhwala am'mimba, maantibayotiki, mankhwala oletsa khansa ndi mankhwala ena. Kuphatikiza apo, phthalic anhydride ndi njira yokonzekera mahomoni osiyanasiyana a zomera monga kukula kwa mahomoni ndi auxin, zomwe ndizofunikira kwambiri pakulimbikitsa kukula kwa zomera ndikuwonjezera zokolola.

Kachiwiri, phthalic anhydride imagwiritsidwanso ntchito kwambiri mumakampani opanga utoto ndi zonunkhira. Monga chopangira utoto ndi zonunkhira, phthalic anhydride imagwiritsidwa ntchito popanga zonunkhira, utoto, utoto wa ulusi wopangidwa, ndi zina zotero. Makhalidwe ake apadera a mankhwala amawapangitsa kukhala osasinthika m'magawo awa, ndikuwonjezera mitundu ndi zonunkhira zabwino m'miyoyo ya anthu.

Kuphatikiza apo, phthalic anhydride imagwiranso ntchito yofunika kwambiri popanga mapulasitiki ndi rabala. Ndi chinthu chofunikira kwambiri popanga mankhwala a polima monga polyphenylene ether, polyamide, ndi polyimide. Mankhwala a polima awa ali ndi makhalidwe abwino kwambiri komanso kukhazikika kwa mankhwala, ndipo amagwiritsidwa ntchito kwambiri m'magalimoto, zamagetsi, zomangamanga ndi zina, zomwe zimathandiza kwambiri pakukula kwa anthu amakono.

Mu gawo la kapangidwe ka organic, phthalic anhydride imagwiritsidwa ntchito m'njira zosiyanasiyana. Itha kugwiritsidwa ntchito pa carbonylation, propylene oxidation, kukonzekera ma activated carbon esters, dry hydrogenation, aldehyde ndi ketone esterification, nitric acid ndi alkaline oxidation. Mu kapangidwe ka inorganic, phthalic anhydride ingagwiritsidwe ntchito popanga ammonium salts, komanso ingagwiritsidwe ntchito ngati polymerization agent yayikulu pakupanga copper zinc sulfide. Machitidwe opangidwa awa amapereka maziko olemera azinthu zopangidwira chitukuko cha makampani opanga mankhwala.

Kuphatikiza apo, phthalic anhydride imagwiranso ntchito yofunika kwambiri pakupanga mankhwala abwino. Ingagwiritsidwe ntchito pogawa makristalo osiyanasiyana ndi ma catalytic reactions, komanso ingagwiritsidwe ntchito pokonzekera ndi kufalitsa ukadaulo wa ma polima osiyanasiyana a calcium sulfure. Pokonza migodi, phthalic anhydride ingagwiritsidwe ntchito pokonza mchere wa miyala kuti iwonjezere magwiridwe antchito a migodi ndi mtundu wa miyala. Kuphatikiza apo, phthalic anhydride ingagwiritsidwenso ntchito ngati zopangira mankhwala ophera tizilombo ndi mankhwala ophera tizilombo, zomwe zimathandiza kwambiri pakuwonetsetsa kuti mbewu zikula komanso kuti zokolola zikule.

Mu mafakitale, phthalic anhydride imagwiritsidwa ntchito makamaka ngati chosungunulira ndi chotulutsa. Chifukwa cha kutentha kwake kochepa komanso kusungunuka kwakukulu, phthalic anhydride imagwiritsidwa ntchito kwambiri m'mafakitale oyenga mafuta ndi petrochemical ngati zopangira zosweka. Nthawi yomweyo, ingagwiritsidwenso ntchito ngati chosinthira kusanthula kwa chromatographic komanso chochotsera zonunkhira, ndi zina zotero, kupereka njira yothandiza yowunikira mankhwala ndi kuchotsa zonunkhira.

Kuphatikiza apo, phthalic anhydride ingagwiritsidwenso ntchito kukonzekera vanillin, kudziwa shuga mkodzo, kukonzekera mitundu yosiyanasiyana ya synergists ndi antifreeze, ndi zina zotero. Ndi chimodzi mwa zipangizo zopangira polyvinyl chloride stabilizers komanso chisankho chabwino chochizira pamwamba pa chitsulo. Pakupanga rabara ndi pulasitiki, phthalic anhydride ingagwiritsidwe ntchito ngati chowonjezera cha rabara ndi pulasitiki kuti iwonjezere magwiridwe antchito ndi ubwino wa chinthucho.
