I-Phthalic Anhydride engu-99%, Ilungele Ukuthunyelwa ~

Isicelo:

Okokuqala, i-phthalic anhydride idlala indima ebalulekile emkhakheni wokukhiqiza imithi. Iyinto ebalulekile yokwenziwa kwemithi yokulwa nokuvuvukala, imithi yokugaya ukudla, ama-antibiotic, imithi yokulwa nomdlavuza kanye neminye imithi. Ngaphezu kwalokho, i-phthalic anhydride nayo iyisandulela sokulungiswa kwama-hormone ahlukahlukene ezitshalo njenge-growth hormone kanye ne-auxin, okubaluleke kakhulu ekukhuthazeni ukukhula kwezitshalo kanye nokwandisa isivuno sezitshalo.

Okwesibili, i-phthalic anhydride isetshenziswa kabanzi embonini yodayi nezinongo. Njengendlela yokuxhumana yodayi nezinongo, i-phthalic anhydride isetshenziselwa ukwenza izinongo, imibala, udayi wefayibha yokwenziwa, njll. Izakhiwo zayo zamakhemikhali ezihlukile ziyenza ingathathelwa indawo kulezi zinsimu, zengeza imibala ecebile namaphunga empilweni yabantu.

Ngaphezu kwalokho, i-phthalic anhydride nayo idlala indima ebalulekile ekukhiqizweni kwepulasitiki nerabha. Iyinto ebalulekile yokusetshenziswa ekukhiqizweni kwamakhemikhali e-polymer njenge-polyphenylene ether, i-polyamide, ne-polyimide. Lawa makhemikhali e-polymer anezakhiwo ezinhle kakhulu zomzimba kanye nokuqina kwamakhemikhali, futhi asetshenziswa kabanzi ezimotweni, kuma-elekthronikhi, ekwakheni nakwamanye amasimu, enikeza ukwesekwa okuqinile ekuthuthukisweni komphakathi wanamuhla.

Emkhakheni wokwenziwa kwezinto eziphilayo, i-phthalic anhydride inezinhlobo eziningi zezicelo. Ingasetshenziswa ekwenzeni i-carbonylation, i-propylene oxidation, ukulungiselela ama-activated carbon esters, i-dry hydrogenation, i-aldehyde ne-ketone esterification, i-nitric acid kanye ne-alkaline oxidation. Ekuhlanganisweni kwezinto eziphilayo, i-phthalic anhydride ingasetshenziswa ukwenza usawoti we-ammonium, futhi ingasetshenziswa njenge-ejenti eyinhloko yokwenza i-polymerization yokwenziwa kwe-copper zinc sulfide. Lokhu kusabela kokwenziwa kunikeza isisekelo sezinto ezicebile zokuthuthukiswa kwemboni yamakhemikhali.

Ngaphezu kwalokho, i-phthalic anhydride nayo inezicelo ezibalulekile emkhakheni wamakhemikhali amahle. Ingasetshenziswa ekuhlukaniseni amakristalu ahlukahlukene kanye nokusabela kwe-catalytic, futhi ingasetshenziswa nasekulungiseleleni nasekusabalaliseni ubuchwepheshe be-polymers e-calcium sulfur ehlukahlukene engaphili. Ekucubungulweni kwezimayini, i-phthalic anhydride ingasetshenziswa ekucubungulweni kwamaminerali ama-ore deposits ukuze kuthuthukiswe ukusebenza kahle kokumba kanye nekhwalithi ye-ore. Ngaphezu kwalokho, i-phthalic anhydride ingasetshenziswa futhi njengezinto zokusetshenziswa kwemithi yokubulala izinambuzane kanye nemithi yokubulala izinambuzane, idlala indima ebalulekile ekuqinisekiseni ukukhula kwezitshalo kanye nokwandisa isivuno.

Ekukhiqizweni kwezimboni, i-phthalic anhydride isetshenziswa kakhulu njengesinyibilikisi kanye nesikhiphi. Ngenxa yokuthi iphansi kakhulu ekubileni kanye nokuncibilika kwayo okuphezulu, i-phthalic anhydride isetshenziswa kabanzi ezimbonini zokuhluza uphethiloli kanye nezimboni ze-petrochemical njengezinto zokusetshenziswa eziqhekekayo. Ngesikhathi esifanayo, ingasetshenziswa futhi njenge-reagent yokuhlaziya i-chromatographic kanye nesikhiphi sezinongo, njll., okuhlinzeka ngendlela ephumelelayo yokuhlaziya amakhemikhali kanye nokukhipha izinongo.

Ngaphezu kwalokho, i-phthalic anhydride ingasetshenziswa futhi ukulungisa i-vanillin, ukunquma ushukela womchamo, ukulungiselela izinhlobo ezahlukene ze-synergists kanye ne-antifreeze, njll. Futhi ingenye yezinto zokusetshenziswa zokwenza iziqinisi ze-polyvinyl chloride kanye nokukhetha okuhle kokwelashwa kwendawo yensimbi. Ekukhiqizeni irabha nepulasitiki, i-phthalic anhydride ingasetshenziswa njengesithasiselo serabha kanye nesithasiselo sepulasitiki ukuthuthukisa ukusebenza komkhiqizo kanye nekhwalithi.
