Intshayelelo
I-3,4-Dibromopyridine (i-CAS # 13534-90-2) i-organic compound kunye ne-chemical formula C5H3Br2N. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
I-3,4-Dibromopyridine yinto eqinileyo engenambala ukuya kumthubi nenevumba elimnandi elahlukileyo. I-soluble kwi-solvents eziphilayo ezifana ne-ethanol, i-chloroform kunye ne-dimethylformamide kwiqondo lokushisa eliqhelekileyo. Ibonisa indawo ephezulu yokunyibilika kunye neyokubilisa.
Sebenzisa:
I-3,4-Dibromopyridine inezicelo ezibalulekileyo kwi-organic synthesis. Ingasetyenziswa njenge catalyst okanye reaction intermediate ukuthatha inxaxheba kwiintlobo ngeentlobo reactions eziphilayo, ezifana Suzuki coupling reaction, C-C bond formation reaction, etc. Ukongeza, ingasetyenziswa ekulungiseleleni amachiza, iidayi kunye. iikhompawundi zepolymer.
Indlela yokulungiselela:
Indlela yokulungiselela i-3,4-dibromopyridine ilula. Enye indlela eqhelekileyo kukusabela kwi-pyridine kunye ne-bromine phantsi kweemeko ezifanelekileyo zokuphendula ukuvelisa i-3,4-dibromopyridine. Ukuphendula kungenziwa kwiqondo lokushisa eliqhelekileyo okanye phantsi kokufudumala.
Ulwazi ngoKhuseleko:
Ingqalelo yokhuseleko iyafuneka xa uphatha i-3,4-dibromopyridine. Inokubangela ukucaphuka okanye ukonakala kwamehlo, ulusu, kunye nenkqubo yokuphefumla. Ngoko ke, izixhobo ezifanelekileyo zokukhusela ezifana neeglasi zokhuseleko, iiglavu kunye nempahla yokukhusela kufuneka inxibe ngexesha lokusebenza. Kuphephe ukuphefumla umphunga wayo, kwaye kungcono usebenze kwindawo engenamoya. Xa ulahla inkunkuma, qwalasela imigaqo yendawo kwaye uyilahle ngokuchanekileyo. Ukuba unayo nayiphi na impilo okanye ukhuseleko, kufuneka ujike ngokukhawuleza kwingcali.
