1,2,4-Benzenetricarboxylicanhydride CAS:552-30-7

I-1,2,4-Benzenetricarboxylic anhydride (BTCA) isebenza imisebenzi eminingi emikhakheni ehlukene ngenxa yezakhiwo zayo eziguquguqukayo. Emkhakheni we-polymer chemistry, isebenza njenge-ejenti yokuxhumanisa kanye ne-monomer esabelayo ekukhiqizweni kwama-thermoset resins, njenge-polyester kanye nama-epoxy resins. Lawa ma-resins athola ukusetshenziswa kokumboza, okunamathelayo, okuhlanganisiwe, kanye namakhemikhali okubumba, okufaka isandla ekuthuthukisweni kwamandla ezinto ezibonakalayo, ukumelana nokushisa, kanye nokuqina kwamakhemikhali. Ngaphezu kwalokho, i-BTCA isetshenziswa ekukhiqizweni kwama-polymer asebenza kahle njenge-polyimides, lapho isebenza khona njengebhloko yokwakha ebalulekile. Ukufakwa kwayo kumaketanga e-polymer kuthuthukisa ukuzinza kwawo kokushisa, amandla omshini, kanye nezakhiwo ze-dielectric, okwenza ifaneleke ukusetshenziswa kuma-elekthronikhi, ezindizayo, kanye namafilimu akhethekile. Ekwakhekeni kokumboza okumelana nokugqwala kanye nama-lining, i-BTCA idlala indima ebalulekile njenge-ejenti yokwelapha kanye ne-crosslinker. Uma ihlanganiswa nezinhlelo ze-epoxy noma ze-polyurethane, ithuthukisa ukumelana kwamakhemikhali kanye nokunamathela kokumboza okusetshenziselwa ukuvikela izindawo zensimbi ezisetshenziswa olwandle, ezimbonini, kanye nengqalasizinda. Ngaphezu kwalokho, isetshenziswa njenge-ejenti ye-chelating ezinqubweni zokwelashwa kwamanzi. Amandla ayo okuqoqa ama-ion ensimbi asiza ekuvimbeleni ukwakheka kwezikali nokugqwala ezinhlelweni zokusatshalaliswa kwamanzi, okufaka isandla ekuthuthukiseni ikhwalithi yamanzi kanye nokuphila isikhathi eside kwengqalasizinda. Ngaphezu kwalokho, i-BTCA isebenza njengesandulela ekuhlanganisweni kwezinto ezisetshenziswa kwezokwelapha kanye namakhemikhali akhethekile. Ukusebenza kwayo kanye namaqembu asebenzayo kwenza kube wusizo ekuthuthukisweni kwamakhemikhali amakhemikhali enziwe ngokwezifiso afanele izidingo ezithile zezimboni nezemithi. Ngaphezu kwalokho, isetshenziswa ekukhiqizweni kwezinto ezivimbela ilangabi kanye nezithasiselo ezingamelani nokushisa zepulasitiki nezindwangu, okufaka isandla ekuthuthukiseni ukuphepha komlilo kanye nokuzinza kokushisa ezinhlotsheni ezahlukahlukene zabathengi nezezimboni. Sekukonke, ukusetshenziswa okuhlukahlukene kwe-anhydride engu-1,2,4-benzenetricarboxylic kuhlanganisa i-polymer chemistry, ama-polymer asebenza kahle kakhulu, izembozo ezingamelani nokugqwala, ukwelashwa kwamanzi, imithi, izinto ezivimbela ilangabi, kanye namakhemikhali akhethekile. Izakhiwo zayo eziguquguqukayo zinegalelo ekuthuthukiseni ukusebenza kwezinto, ukuvikela ekuwohlokeni, kanye nokwenza kube lula ukukhiqizwa kwezinto ezithuthukisiwe ezimbonini eziningi.
