I-anhydride ye-maleiciyinhlanganisela yamakhemikhali enemisebenzi eminingi ethole inhlobonhlobo yokusetshenziswa kuzo zonke izimboni ezahlukene. Izici zayo eziyingqayizivele nokusebenza kabusha kuyenza ibe isithako esibalulekile ekukhiqizweni kwemikhiqizo eminingi. Kusukela kuma-polymers kuya kwezemithi, i-maleic anhydride idlala indima ebalulekile ekuthuthukiseni ukusebenza nokusebenza kwezinto ezihlukahlukene.
Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-maleic anhydride isekukhiqizweni kwezinsalela ze-polyester ezingagcwele. Lawa ma-resin asetshenziswa kakhulu ekwenzeni amapulasitiki aqiniswe nge-fiberglass, izingxenye zezimoto, kanye nezicelo zasolwandle. Ikhono le-anhydride ye-maleic lokuthola i-copolymerization nge-styrene liphumela ezinsikeni ezinamandla amakhulu, ukuqina, nokumelana nokugqwala.
Ngaphezu kwendima yayo ekukhiqizeni i-polymer, i-maleic anhydride iphinde isetshenziswe ekuhlanganiseni amakhemikhali ezolimo. Isebenza njengesakhiwo sokukhiqiza izibulala-khula, izibulala-zinambuzane, nezibulala-sikhunta, okunikela ekuvikelweni kwezitshalo nasekuthuthukiseni umkhiqizo wezolimo.
Ngaphezu kwalokho, i-anhydride ye-maleic iyingxenye ebalulekile ekwenziweni kwama-polymers ancibilika emanzini, athola ukusetshenziswa ezimbonini ezahlukahlukene, okubandakanya izinto zokunamathisela, okokunamathela, kanye nemikhiqizo yokunakekela umuntu. Lawa ma-polymers anikeza izinzuzo ezinjengokunamathela okuthuthukisiwe, izakhiwo zokwakha ifilimu, nokulawulwa kwe-rheological, okuwenza abaluleke ezinhlobonhlobo zokubunjwa.
Imboni eyenza imithi iphinde izuze ekusetshenzisweni kwe-maleic anhydride ekukhiqizeni ama-intermediate emithi kanye nezinhlelo zokulethwa kwezidakamizwa. Ukusebenza kabusha kwayo kanye namaqembu asebenzayo kunika amandla ukuguqulwa kwama-molecule ezidakamizwa, okuholela ekuncibilikeni okuthuthukisiwe, i-bioavailability, kanye nokulethwa okuhlosiwe.
Ngaphezu kwalokho, i-maleic anhydride isetshenziswa ekukhiqizeni ama-ejenti okulinganisa amaphepha, athuthukisa amandla nokuphrinta kwemikhiqizo yephepha. Ikhono layo lokwenza ama-complexes azinzile ngezinhlanganisela ezihlukahlukene likwenza kube isithasiselo esibalulekile enqubweni yokukhiqiza iphepha.
Sengiphetha, ukusebenzisana kwe-maleic anhydride kubonakala ekusetshenzisweni kwayo okusabalele kuzo zonke izimboni. Iqhaza layo ekukhiqizweni kwe-polymer, ezolimo, ukunakekelwa komuntu siqu, ezemithi, nokukhiqizwa kwephepha kugqamisa ukubaluleka kwayo njengesakhiwo esibalulekile ekuthuthukisweni kwezinto ezintsha nemikhiqizo. Njengoba ucwaningo nobuchwepheshe buqhubeka buthuthuka, amandla e-maleic anhydride okufaka isandla ezinhlelweni ezintsha nezithuthukisiwe asalokhu ethembisa.
