Intshayelelo
I-2-Bromoisoniacin, eyaziwa ngokuba yi-2-bromopyridine-4-carboxylic acid, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-bromoisoniacinic acid:
Umgangatho:
- Imbonakalo: I-2-Bromoisoniacinic acid iyikristale emhlophe okanye emhlophe eqinileyo.
- Ukunyibilika: Inokunyibilika kwizinyibilikisi eziphilayo ezifana namanzi, i-ethanol, kunye ne-ether.
- Iimpawu zeMichiza: Inokuthi ingene kwi-alkaline hydrolysis reactions phantsi kweemeko ze-alkaline ukuvelisa iikhompawundi ezihambelana ne-bromopyridine.
Sebenzisa:
- Inokusetyenziswa njengedayi ephakathi kwi-synthesis yedayi kunye ne-pigments.
Indlela:
- Indlela eqhelekileyo yokulungiselela i-2-bromoisoniacinic acid ifunyenwe ngokuphendula i-2-picolinic acid kunye ne-thionyl bromide. Xuba i-2-picolinic acid kunye ne-sulfoxide kwi-solvent efanelekileyo kwaye ungeze i-catalyst ethile ye-acidic. Emva koko, i-thionyl bromide yongezwa kancinci, kwaye ukusabela kwenzeka. Isisombululo sokusabela siphathwe ngokufanelekileyo kwaye sihlanjululwe ukufumana imveliso ye-2-bromoisoniacinic acid enobunyulu obuphezulu.
Ulwazi ngoKhuseleko: Yinto ecaphukisayo enokubangela ukucaphuka kunye nokungakhululeki xa udibana nolusu, amehlo, okanye umjelo wokuphefumla. Izixhobo ezifanelekileyo zokuzikhusela ezinjengeeglavu, iindondo, izikhuselo zobuso zifanele zinxitywe xa zisetyenziswa.
- Xa uphethe i-2-bromoisoniacin, kuphephe ukuphefumla uthuli lwayo okanye umphunga. Emva kokunyanga, iindawo ezingcolileyo kunye nezixhobo kufuneka zicocwe kakuhle.
- Ukugcinwa ngokufanelekileyo kwe-2-bromoisoniacin, kufuneka igcinwe kwindawo eyomileyo, epholileyo kunye nendawo enomoya, kude nokutshisa kunye ne-oxidants. Gcina ngokwahlukileyo kwizinto ezinokutsha, i-acids kunye nee-agent zokunciphisa.
- Kwimeko yokuphefumla ngempazamo, ukuvezwa, okanye ukungeniswa kwe-2-bromoisoniacin, funa unyango ngokukhawuleza kwaye uze nemiyalelo okanye ileyibhile yemveliso ekuthethwa ngayo.
