Sebelisa:

- 2,3,5-Tribromopyridine e atisa ho sebelisoa e le reagent le e bohareng ba motsoako oa manyolo.

-E sebelisoa haholo masimong a motsoako oa lithethefatsi, tlhahiso ea chefo e bolaeang likokoanyana le ho lokisa dae.

-Ho feta moo, e ka boela ea sebelisoa e le ntho e qalang bakeng sa ho qaptjoa ha metsoako ea metsoako ea tšepe (ho kenyeletsoa li-polymers tsa ho hokahanya le lisebelisoa tsa photoelectric).

 

Mokhoa oa ho itokisa:

Mokhoa oa ho itokisa oa 2,3,5-Tribromopyridine o ka finyelloa ka mehato e latelang:

Ntlha ea pele, pyridine e qhibiliha ka har'a motsoako oa lintho tse phelang tse kang dichloromethane kapa chloroform.

2. Eketsa bromine ho tharollo 'me u chese karabelo.

3. Ka mor'a ho phethoa ha karabelo, sehlahisoa sa brominated se ne se hydrolyzed ka ho eketsoa ha metsi.

4. Qetellong, sehlahisoa se arotsoe 'me se hloekisoa ka ho hloekisa, crystallization, joalo-joalo.

 

Lintlha tsa Tšireletseho:

- 2,3,5-Tribromopyridine e ke ke ea baka mathata a tšireletso tlas'a maemo a tloaelehileng a ho sebetsa.

-E ka baka ho teneha letlalong, mahlo le pampitšana ea phefumoloho, kahoo roala lisebelisoa tse loketseng tsa ho itšireletsa ha u li sebelisa.

-Sheba mekhoa e nepahetseng ea laboratori le mehato ea polokeho ha u sebetsana le motsoako ona.

-Ha u boloka le ho sebetsana le motsoako, ho lokela ho nkoa tlhokomelo ho qoba ho kopana le li-oxidants, li-acids tse matla, metheo e matla le lintho tse ling.
