I-2-Bromo pyridine (CAS# 109-04-6)
Isingeniso esifushane
I-2-Bromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- 2-Bromopyridine uketshezi olungenambala ukuya kokuphuzi olunokunambitheka okukhethekile okunephunga elimnandi.
- I-2-Bromopyridine iyancibilika kancane emanzini, kodwa ayincibiliki futhi incibilika kalula kuzincibilikisi zemvelo njenge-ethanol ne-ether.
Sebenzisa:
I-2-Bromopyridine iyi-reagent esetshenziswa kakhulu emkhakheni we-organic synthesis. Ngokuvamile isetshenziswa njenge-catalyst, ligand, intermediate, njll.
Indlela:
I-2-Bromopyridine ingalungiswa ngezindlela ezimbili eziyinhloko:
1. Emazingeni okushisa asekamelweni, i-bromine ilungiswa ngokusabela nge-pyridine.
2. I-Ethyl bromoketone kanye ne-pyridine reaction isetshenziselwa ukuthola i-2-bromopyridine.
Ulwazi Lokuphepha:
- I-2-Bromopyridine iyinhlanganisela ye-organohalogen enobuthi obuthile. Ukuchayeka kuwo noma ukuwuhogela kungase kubangele ukulimala empilweni yomuntu.
- Lapho usetshenziswa, gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela.
- Kufanele igcinwe kude nezinto ezivuthayo nezinokushisa okuphezulu futhi igcinwe endaweni epholile, engenawo umoya.
- Uma kulahlwa imfucuza, kufanele ilahlwe ngokuhambisana nemithetho yendawo kanye nemithethonqubo ukuze kugwenywe ukungcoliswa kwemvelo.
- Ngaphambi kokusebenzisa i-2-bromopyridine, qiniseka ukuthi ufunda futhi ulandele ishidi ledatha yokuphepha yomkhiqizo kanye nemihlahlandlela yokusebenza efanele.
