I-2-Bromo pyridine (CAS# 109-04-6)
Intshayelelo emfutshane
I-2-i-Bromopyridine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- 2-Bromopyridine lulwelo olungenambala ukuya kumthubi kunye nencasa ekhethekileyo enevumba elimnandi.
I-2-Bromopyridine inyibilika kancinane emanzini, kodwa ayinyibiliki kwaye inyibilika ngokulula kwizinyibilikisi zezinto eziphilayo ezifana ne-ethanol kunye ne-ether.
Sebenzisa:
- I-2-Bromopyridine i-reagent esetyenziswa ngokubanzi kwintsimi ye-organic synthesis. Isetyenziswa ngokuqhelekileyo njenge-catalyst, ligand, intermediate, njl.
Indlela:
I-2-Bromopyridine inokulungiswa ngeendlela ezimbini eziphambili:
1. Kwiqondo lokushisa lokushisa, i-bromine ilungiswa ngokuphendula nge-pyridine.
2. I-Ethyl bromoketone kunye ne-pyridine reaction isetyenziselwa ukufumana i-2-bromopyridine.
Ulwazi ngoKhuseleko:
- I-2-Bromopyridine yi-organohalogen compound kunye netyhefu ethile. Ukuba sesichengeni okanye ukuphefumla kuyo kunokubangela ingozi kwimpilo yabantu.
- Xa usetyenziswa, nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi, kunye nempahla yokukhusela.
- Kufuneka igcinwe kude nezinto ezinokutsha kunye nobushushu obuphezulu kwaye igcinwe kwindawo epholileyo nengena umoya.
- Xa ulahla inkunkuma, kufuneka ilahlwe ngokungqongqo ngokuhambelana nemithetho kunye nemimiselo yendawo ukuphepha ukungcoliseka kwendalo.
- Ngaphambi kokusebenzisa i-2-bromopyridine, qiniseka ukuba ufunda kwaye ulandele iphepha ledatha yokhuseleko lwemveliso kunye nezikhokelo zokusebenza ezifanelekileyo.
