I-2,3-Dibromopyridine (CAS # 13534-89-9) isingeniso

I-2,3-dibromopyridine yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokwenza, kunye nolwazi lokhuseleko:
indalo:
-2,3-dibromopyridine yinto eqinileyo engenambala ukuya kumthubi nenuka kamnandi.
-I-soluble kwi-solvents ye-organic efana ne-ethanol, i-dimethylformamide, kunye ne-dichloromethane kwiqondo lokushisa, kodwa ayinakuchithwa emanzini.
-Le khompawundi inobuntununtunu ekukhanyeni nasemoyeni kwaye kufuneka igcinwe kwisikhongozeli esivaliweyo kude nokukhanya.
Injongo:
-2,3-dibromopyridine isetyenziswa ngokuqhelekileyo njengento ebalulekileyo ephakathi kwi-organic synthesis.
-Ingasetyenziselwa ukutshintshwa kunye neempendulo ze-condensation kwi-organic synthesis.
Indlela yokuvelisa:
-Indlela eqhelekileyo yokulungiselela i-2,3-dibromopyridine yi-bromination reaction ye-pyridine.
-Indlela esetyenziswa ngokuqhelekileyo yokulungiselela ukutshisa i-pyridine kumanzi e-bromine agxininisiweyo ukuze aphendule, kunye nesiphumo se-2,3-dibromopyridine i-precipitates kwisisombululo sokuphendula emva kokupholisa.
Ulwazi lokhuseleko:
-2,3-dibromopyridine yinto ecaphukisayo enokubangela ukucaphuka kwamehlo kunye nolusu xa udibana.
-Izixhobo ezifanelekileyo zokukhusela ezifana neiglavu, izibuko, kunye nempahla yokukhusela kufuneka ifakwe ngexesha lokusebenza.
-Kuphephe ukuphefumla uthuli okanye igesi yayo, kwaye usebenze kwindawo engena umoya.
