I-phthalic anhydrideiyinhlanganisela yamakhemikhali ebalulekile edlala indima ebalulekile embonini yokukhiqiza. Izakhiwo zayo eziguquguqukayo ziyenza ibe yisithako esibalulekile ekukhiqizeni imikhiqizo ehlukahlukene, kusukela kumapulasitiki nama-resin kuya odayi nemithi. Kulokhu okuthunyelwe kwebhulogi, sizohlola ukusetshenziswa kanye nokubaluleka kwe-phthalic anhydride embonini yamakhemikhali.
Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-phthalic anhydride isekukhiqizweni kwamapulasitiki e-phthalate, asetshenziselwa ukwenza i-PVC (i-polyvinyl chloride) iguquguquke futhi iqine. Lawa ma-plasticizer abalulekile ekusetshenzisweni okubanzi, okuhlanganisa izintambo nezintambo, i-flooring, kanye nemishini yezokwelapha. Ngaphandle kwe-phthalic anhydride, ukukhiqizwa kwalezi zinto ezibalulekile kungavinjelwa kakhulu.
I-Phthalic anhydride iphinde ibe yisithako esibalulekile ekukhiqizeni izinsalela ze-polyester ezingagcwele, ezisetshenziswa kakhulu ekwenzeni amapulasitiki aqiniswe nge-fiberglass. Lawa ma-resin asetshenziswa ezimbonini zezimoto, ezokwakha, nezasolwandle, phakathi kwezinye, ngenxa yamandla azo amangalisayo, ukuqina kwawo, nokungagqwali kwawo. Ngaphandle kwe-phthalic anhydride, ukukhiqizwa kwalawa ma-resin abalulekile bekungeke kwenzeke.
Ngaphezu kwamapulasitiki nama-resin, i-phthalic anhydride ibuye isetshenziswe ekukhiqizeni odayi nezingulube. Ihlangana namakhemikhali ahlukahlukene ukwenza inhlanganisela enemibala esetshenziswa ezimbonini zendwangu, iphepha, nepulasitiki. Lawa madayi nama-pigments abalulekile ekukhiqizweni kwezinhlobonhlobo zemikhiqizo, kusukela ekugqokeni nasekupakishweni kuya ezintweni eziphrintiwe nasezimpahleni zabathengi.
Ngaphezu kwalokho, i-phthalic anhydride iyisithako esibalulekile ekukhiqizweni kwemithi ethile namakhemikhali ezolimo. Isetshenziswa ekuhlanganiseni kwemithi ehlukahlukene kanye nezibulala-zinambuzane, okunomthelela ekuthuthukisweni kwezempilo nezolimo. Ngaphandle kwe-phthalic anhydride, ukukhiqizwa kwalawa makhemikhali abalulekile kungaba nomthelela omkhulu.
Naphezu kokusetshenziswa kwayo okuhlukahlukene, kubalulekile ukuqaphela ukuthi i-phthalic anhydride iphakamise ukukhathazeka mayelana nemithelela yayo engaba khona empilweni kanye nemvelo. Kubalulekile ukuthi abakhiqizi baphathe futhi basebenzise i-phthalic anhydride ngokuzibophezela ukuze banciphise ubungozi obungaba khona. Ukwengeza, abacwaningi nososayensi bahlala behlola ezinye izinhlanganisela nezindlela zokukhiqiza ukubhekana nalokhu kukhathazeka nokudala izixazululo ezizinzile.
Sengiphetha, i-phthalic anhydride iyinhlanganisela yamakhemikhali ebalulekile ebaluleke kakhulu embonini yokukhiqiza. Ukusetshenziswa kwayo okuhlukahlukene ekukhiqizeni amapulasitiki, ama-resin, odayi, imithi, namakhemikhali ezolimo kuyenza ibe isithako esibalulekile emikhiqizweni ehlukahlukene esiyisebenzisa ekuphileni kwethu kwansuku zonke. Njengoba imboni iqhubeka nokuthuthuka, kubalulekile ukubeka eqhulwini ukusetshenziswa okunesibopho nokuqhubekayo kwe-phthalic anhydride ukuze kuncishiswe imithelela engaba khona empilweni yabantu kanye nemvelo.
