Isingeniso
I-2-methyl-3-bromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:
Ikhwalithi:
I-2-Methyl-3-bromopyridine iwuketshezi olungenambala olunephunga elimnandi elifana ne-pyridine.
Sebenzisa:
I-2-Methyl-3-bromopyridine ivame ukusetshenziswa njenge-reagent futhi iphakathi ku-organic synthesis.
Indlela:
Ngokuvamile, ukulungiswa kwe-2-methyl-3-bromopyridine kungafinyelelwa ngokusabela kwe-bromination ye-pyridine. Indlela yokuhlanganisa evame ukusetshenziswa ukusabela i-2-methylpyridine ne-bromine ku-solvent ephilayo njenge-chloroform, kusetshenziswa i-sodium hydroxide njenge-catalyst.
Ulwazi Lokuphepha: Yinto enobuthi engase ibangele ukucasuka nokulimala ohlelweni lokuphefumula lomuntu, isikhumba, namehlo. Izinto zokuzivikela ezifanele ezinjengamagilavu amakhemikhali, izibuko zamehlo nezingubo zokuzivikela kumelwe zigqokwe lapho zisetshenziswa futhi kugwenywe ukuthintana ngokuqondile. Ngesikhathi sokugcina nokuphatha, kuyadingeka ukunaka umlilo nokukhanya, futhi uqinisekise ukuthi ugcinwa kude nomlilo kanye nemithombo yokushisa. Okubaluleke kakhulu, landela izinqubo eziphephile zokusebenza zamakhemikhali futhi ulandele imithethonqubo efanele.
