Intshayelelo
I-2-Fluoro-3-chloro-5-bromopyridine i-organic compound.
Ikhompawundi iqinile kunye nembonakalo yekristale emhlophe ukuya kumthubi. Ayinyibiliki emanzini kwiqondo lobushushu begumbi, kodwa inokunyibilika kwezinye izinyibilikisi eziphilayo ezifana ne-methanol kunye ne-methylene chloride.
I-3-Bromo-5-chloro-6-fluoropyridine inexabiso elithile lesicelo kwi-organic synthesis. Ihlala isetyenziswa njengendawo ephakathi kwiimpendulo ezahlukeneyo kwi-organic synthesis, efana neempendulo ezidibanisayo kunye nearomatics yehydrocarbon functionalization reactions. Ezi mpendulo zinokudlala indima ebalulekileyo ekwakhiweni kwezakhiwo ze-organic molecular.
Indlela yokulungiselela i-3-bromo-5-chloro-6-fluoropyridine inokuqhutywa ngeendlela ezahlukeneyo. Indlela eqhelekileyo kukwenza inyathelo le-halogenation reaction ngokusebenzisa izinto ezihambelanayo zepyridine, kuqala ukwazisa ifluorine kwindawo yesi-3, emva koko i-chlorine kwindawo yesi-5, kwaye ekugqibeleni ibromine kwindawo yesi-6.
Ulwazi lokhuseleko: I-3-Bromo-5-chloro-6-fluoropyridine yikhemikhali kwaye kufuneka iphathwe ngokuhambelana neenkqubo ezifanelekileyo zokusebenza zokhuseleko. Inokucaphukisa ulusu, amehlo, kunye nepheshana lokuphefumla, kunye nezixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglavu, kunye nempahla yokukhusela kufuneka inxitywe xa usebenza.
Ukugcinwa kunye nokuphathwa kweekhemikhali kufuneka kwakhona kuqhutywe ngokuhambelana nemimiselo efanelekileyo, kwaye ihlelwe kwaye ibhalwe ngokweempawu ezibonakalayo zeekhemikhali. Ekusetyenzisweni, qinisekisa ukungena komoya okufanelekileyo kwaye ugweme ukuphefumla iigesi okanye umphunga.
