3-bromo-2-chloro-6-picoline (CAS# 185017-72-5) Intshayelelo
yinto eqinileyo enombala omhlophe ukuya kumthubi. Indawo yokunyibilika kwayo imalunga ne 63-65 degrees celcius kwaye ubuninzi bayo bumalunga ne 1.6g/cm³. Le khompawundi iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-alcohols kunye ne-ethers kubushushu obuqhelekileyo.
Sebenzisa:
Ihlala isetyenziswa njenge-reagent kwaye iphakathi kwi-organic synthesis. Ingasetyenziselwa njenge-catalyst, i-oxidant kunye ne-reductant ye-synthesis yeentlobo ezahlukeneyo ze-organic compounds. Ukongezelela, ingasetyenziselwa ukulungiswa kwezithako ezisebenzayo kunye ne-antimicrobial agents kwicandelo lezonyango.
Indlela:
Inokudityaniswa ngeendlela ezahlukeneyo. Enye yeendlela eziqhelekileyo ukusabela kwi-pyridine kunye ne-bromoacetate, kwaye emva koko uphendule nge-chloride yobhedu ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
Xa usebenzisa kunye nokuphatha: Nika ingqalelo kule miba yokhuseleko ilandelayo:
-Le ngqungquthela inamandla okubangela ukucaphuka kunye nomonakalo kwindlela yokuphefumula, amehlo kunye nesikhumba, kunye nokudibanisa ngokuthe ngqo kufuneka kugwenywe.
-ekusetyenzisweni kwenkqubo kufuneka kugwenywe ukuphefumla uthuli okanye i-steam, isidingo sokugcina iimeko ezifanelekileyo zomoya.
-Izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, izibuko kunye nempahla yokukhusela kufuneka inxibe ngexesha lokusetyenziswa.
-Musa ukugcina okanye udibanise le ngqungquthela kunye ne-oxidants eqinile, i-acids eqinile okanye iziseko ezinamandla ukuphepha ukuphendula okuyingozi.
-Xa ulahla inkunkuma, kuyimfuneko ukuqhuba ukuphathwa ngokufanelekileyo kunye nokulahla ngokuhambelana nemimiselo yendawo.
