Isingeniso
I-2-Amino-3-cyanopyridine iyinhlanganisela ye-organic ifomula yayo yesakhiwo i-C6H5N3. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Izakhiwo: I-2-Amino-3-cyanopyridine iyikristalu eqinile, ngokuvamile emhlophe noma ephuzi ngokukhanyayo. Iyazinza uma kuqhathaniswa nezinga lokushisa legumbi futhi inokuncibilika okuphansi emanzini.
Inhloso: I-2-Amino-3-cyanopyridine ingasetshenziswa njengento ebalulekile eluhlaza futhi ephakathi ku-organic synthesis. Ivamise ukusetshenziselwa ukuhlanganisa inhlanganisela yezinto eziphilayo ezisebenzayo, njengezidakamizwa, izibulala-zinambuzane kanye nodayi. Ngaphezu kwalokho, ibuye isetshenziswe kabanzi ekuhlanganiseni odayi bensimbi be-phthalocyanine kanye nokulungiswa kwezinhlanganisela ze-heterocyclic.
Indlela yokulungiselela: I-2-Amino-3-cyanopyridine ijwayele ukulungiswa ngokusebenzisa i-benzaldehyde njengenhlanganisela yokuqala futhi idlule uchungechunge lwezinyathelo zokwenziwa. Indlela evame ukusetshenziswa ukusabela kwe-benzaldehyde nge-aminoacetonitrile ngaphansi kwezimo ezine-acidic ukuze yakhe i-2-Amino-3-cyanopyridine.
Ulwazi lokuphepha: Uma usebenzisa futhi usebenzisa i-2-Amino-3-cyanopyridine, lezi zinyathelo zokuphepha ezilandelayo kufanele zinakwe: Kungase kucasule amehlo, isikhumba kanye nomgudu wokuphefumula, ngakho ukuthintana okuqondile kufanele kugwenywe ngesikhathi sokusebenza. Kufanele isetshenziswe endaweni enomoya omuhle futhi igweme ukuhogela uthuli lwayo. Ngesikhathi esifanayo, ngesikhathi sokuphatha nokugcina, gwema ukuthintana nezinto eziyingozi ezifana nama-oxidants, ama-asidi aqinile nezisekelo eziqinile ukuze ugweme ukusabela okuyingozi okungenzeka. Lapho uphatha le nhlanganisela, izinqubo zokuphepha kufanele zibhekwe ngokuqinile. Uma ithathwe ngephutha noma ihogelwe ngephutha, funa usizo lwezempilo kusenesikhathi.
