Isingeniso
I-2,5-Dibromo-3-nitropyridine (2,5-dibromo-3-nitropyridine) iyinhlanganisela yezinto eziphilayo. Ezinye zezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-2,5-dibromo-3-nitropyridine kunikezwa ngezansi:
Izakhiwo:
- Ukubukeka : I-2,5-Dibromo-3-nitropyridine iqinile ephuzi.
- I-Solubility : I-2,5-Dibromo-3-nitropyridine iyancibilika kuma-solvents ephilayo njenge-ethanol, i-dimethyl sulfoxide ne-dichloromethane futhi ayincibiliki emanzini.
Isebenzisa:
- I-2,5-Dibromo-3-nitropyridine isetshenziswa njengendawo ephakathi ku-organic synthesis.
- Ibuye isetshenziswe ekulungiseleleni i-nitrogen-containing heterocyclic compounds, njenge-pyridine derivatives.
Indlela Yokulungiselela:
- Ukulungiswa kwe-2,5-dibromo-3-nitropyridine kuvame ukwenziwa ukusabela kokwenziwa. Umzila ojwayelekile wokwenziwa ukuthola umkhiqizo ohlosiwe ovela ku-pyridine njengento yokuqala nge-bromination ne-nitration. Izinyathelo eziqondile zokwenziwa zingashintshwa njengoba kudingeka.
Ulwazi Lokuphepha:
I-2,5-Dibromo-3-nitropyridine ayifaki ubungozi bokuphepha obubalulekile ngaphansi kwezimo ezijwayelekile zokusetshenziswa.
- Kodwa-ke, njengekhemikhali, izinqubo ezijwayelekile zokuphepha zaselabhorethri kufanele zilandelwe. Ukuthintana nesikhumba, amehlo kanye nolwelwesi lwamafinyila kufanele kugwenywe. Izinyathelo zokuzivikela ezinjengamagilavu, izibuko kanye nejazi laselabhorethri kufanele zibhekwe ngesikhathi sokuphatha.
- Uma kwenzeka ungenwa ngephutha noma uhogele inhlanganisela, funa usizo lwezokwelapha ngokushesha. Uma uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
