1,4,5,8-Naphthalenetetracarboxylic dianhydride/NTDA cas:81-30-1

Incazelo emfushane:

I-1,4,5,8-naphthalene tetracarboxylic anhydride, evame ukubizwa ngokuthi i-NTA, iwuketshezi olumhlophe oluyikristalu olunefomula yamakhemikhali ethi C12H4O5.Ikhiqizwa ngokucophelela kusetshenziswa izinqubo eziqondile zokuqinisekisa izinga layo eliphezulu nobumsulwa.I-NTA isetshenziswa ngokuyinhloko njengento eluhlaza ekuhlanganisweni kwezinhlanganisela ezihlukahlukene zezinto eziphilayo, okunikela ekuthuthukisweni kwezimboni ezimbalwa ezibalulekile.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

- Izakhiwo Zomzimba Nezamakhemikhali: I-NTA inesisindo semolekyuli esingu-244.16 g/mol kanye nendawo yokuncibilika engu-352-358°C. Ibonisa ukuncibilika okuhle kakhulu kuzincibilikisi zemvelo njenge-chloroform, i-ethyl acetate, ne-benzene.Ukwengeza, kubonisa ukuzinza okuhle ngaphansi kwezimo ezivamile, okuvumela ukugcinwa nokuthutha ngaphandle kokuwohloka okukhulu.

- Izicelo: I-NTA ithola ukusetshenziswa ezinhlobonhlobo zezimboni, ezihlanganisa ezemithi, odayi, namapulasitiki.Emkhakheni wezokwenziwa kwemithi, isebenza njengengxenye ebalulekile ekuhlanganisweni kwezidakamizwa, okunikela ekuthuthukisweni kwezindlela zokwelapha ezintsha.Ukusebenza kabusha kwayo okuphezulu nokuhambisana kwayo kuyenza ibe yingxenye ekahle ekukhiqizweni kwamadayi asebenza kahle kakhulu, iletha izici zombala ezihlukile.Ngaphezu kwalokho, i-NTA isetshenziswa njenge-monomer ekuhlanganisweni kwama-polymer akhethekile nama-resin, ethuthukisa ukusebenza kwawo kukonke kanye nokuqina.

- Ukucatshangelwa Kokuphepha: Lapho ubamba i-1,4,5,8-naphthalene tetracarboxylic anhydride, kuyadingeka ukubheka izinyathelo zokuphepha ezijwayelekile.Le nhlanganisela kufanele igcinwe endaweni epholile, eyomile, kude namalangabi avulekile noma imithombo yokuthungela.Ukungena komoya ngendlela efanele kubalulekile ngesikhathi sokusetshenziswa ukuvimbela ukuhogela kwanoma yimuphi umhwamuko ongaba khona.Njenganoma iyiphi into yamakhemikhali, kubalulekile ukugqoka izinto zokuzivikela ezifanele, okuhlanganisa amagilavu nezibuko, ukuze unciphise ukuthintana okuqondile nokuqinisekisa ukuphepha komuntu siqu.

Ekuphetheni, i-1,4,5,8-naphthalene tetracarboxylic anhydride iyinhlanganisela yamakhemikhali ebalulekile esebenza njengesithako esisebenza ngezindlela ezihlukahlukene ezimbonini ezihlukahlukene.Izakhiwo zayo ezingavamile kanye nokusebenza okubanzi kuyenza ibe yingxenye ebalulekile ekuhlanganiseni izinto eziphilayo, imithi, odayi, namapulasitiki.Sizinikele ekukunikezeni i-NTA yekhwalithi ephezulu kakhulu, ekhiqizwe ngokunemba nangokuhambisana nezindinganiso zomkhakha.
