Selelekela

5-Bromo-2-methyl-3-nitropyridine ke motsoako oa lintho tse phelang.

Thepa: 5-Bromo-2-methyl-3-nitropyridine ke kristale e mosehla ho isa ho lamunu e nang le tatso e khethehileng ea nitro. E tsitsitse mocheso oa kamore, empa ho bola ho ka etsahala ha ho futhumala kapa ho kopana le li-acid tse matla.

E ka boela ea sebelisoa ho tlhahlobo ea lik'hemik'hale, li-biomarker, le organic synthesis.

Mokhoa oa ho itokisa: Mokhoa oa ho lokisa 5-bromo-2-methyl-3-nitropyridine e ka ba nitrification. Mokhoa o tloaelehileng ke ho itšoara ka 2-methylpyridine le concentrated nitric acid ho hlahisa 2-methyl-3-nitropyridine, ebe o sebelisa bromine ho etsa bromination reaction ka pel'a sulfuric acid ho fumana sehlahisoa sa ho qetela.

Tlhahisoleseding ea polokeho: 5-bromo-2-methyl-3-nitropyridine e batla e tsitsitse tlas'a maemo a tloaelehileng a tšebeliso, empa ho ntse ho hlokahala ho ela hloko ts'ebetso e sireletsehileng. Ke ntho e tukang le ho kopana le malakabe a bulehileng kapa mocheso o phahameng o lokela ho qojoa. Lisebelisoa tse loketseng tsa ho itšireletsa, tse kang liatlana tsa laboratori le likhalase tsa tšireletso, li lokela ho roaloa nakong ea ts'ebetso 'me li qobe ho kopana le letlalo le mahlo. Haeba motho a ka kopana ka phoso, hlatsoa hang-hang ka metsi a mangata 'me u batle thuso ea bongaka hang-hang. Litšila li lokela ho bolokoa hantle le ho lahloa ho sireletsa tikoloho.
