Isingeniso
Izakhiwo: Inokuncibilika okuphansi emanzini kanye nokuncibilika okuhle kuzinyibilikisi zemvelo. Izakhiwo zayo zamakhemikhali ziyasebenza futhi zijwayele ukunciphisa, i-alkylation nokunye ukusabela.
Sebenzisa:
I-2-hydroxy-3-nitro-5-chloropyridine inenani elithile lohlelo ku-organic synthesis. Ingasetshenziswa njengengxenye ebalulekile ekuhlanganiseni kwe-organic synthesis futhi ibandakanyeka ekuphenduleni okuningi kwe-organic synthesis, njengokuhlanganiswa kwezinhlanganisela ze-hop flavour.
Indlela:
Kunezindlela eziningi zokulungiselela i-2-hydroxy-3-nitro-5-chloropyridine, indlela evamile itholakala nge-nitrification ye-2-azacyclopentadiene, bese i-hydrogenation eyengeziwe kanye nokusabela kwe-chlorination ukuthola umkhiqizo ohlosiwe.
Ulwazi Lokuphepha:
Gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile, ama-alkali aqinile nezinye izinto ukuze ugweme ukusabela okunobudlova.
Naka izinyathelo zokuzivikela ngesikhathi sokusetshenziswa, futhi gqoka izinto zokuzivikela ezifanele, njengamagilavu okuphepha, izibuko, njll.
Uma usebenzisa noma ugcina, gcina i-2-hydroxy-3-nitro-5-chloropyridine endaweni epholile, enomoya omuhle, kude nomlilo namazinga okushisa aphezulu.
