Isingeniso
I-5-Bromo-2-methylpyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:
Ikhwalithi:
Ukubukeka: I-5-bromo-2-methylpyridine iyikristalu eliphuzi elikhanyayo elingenambala noma eliphaphathekile.
I-Solubility: Ingancibilika kuzincibilikisi eziningi eziphilayo futhi inokuncibilika okuphansi emanzini.
Sebenzisa:
I-Catalyst: Ingasetshenziswa futhi njenge-catalyst yokusabela okuthile okwenziwe.
Indlela:
Indlela evamile yokulungisa i-5-bromo-2-methylpyridine yi-brominated 2-methylpyridine. Izinyathelo eziqondile zimi kanje:
I-2-methylpyridine incibilika ku-solvent.
I-ejenti ye-brominating, efana namanzi e-bromine noma i-mercuric chloride, yengezwa kwisixazululo ukwenza i-5-bromo-2-methylpyridine.
Hlunga futhi ucwebezele ukuze uthole umkhiqizo omsulwa.
Ulwazi Lokuphepha:
I-5-Bromo-2-methylpyridine iyinhlanganisela ye-organobromine futhi kufanele iphathwe ngokucophelela ukugwema ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula.
Gwema ukuhogela impushana yayo noma intuthu ewukhiphayo.
Amagilavu okuzivikela afanelekile, izibuko zokuphepha kanye nemaski okuzivikela kufanele kugqokwe ngesikhathi sokusebenza.
Lapho usebenzisa noma ugcina, kufanele igcinwe kude nokushisa nama-oxidants.
Lapho uphatha i-5-bromo-2-methylpyridine, izinqubo zokusebenza eziphephile kufanele zilandelwe futhi ziphathwe endaweni enomoya omuhle.
