3-Bromo-2,6-dichloropyridine ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C5H2BrCl2N. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
- 3-Bromo-2,6-dichloropyridine e tiile ka sebōpeho sa kristale e tšoeu ho ea ho mosehla.
-Nako ea ho qhibiliha ha eona e ka ba likhato tse 60-62 tsa Celsius, 'me ntlha ea eona e belang e ka ba likhato tse 240 tsa Celsius.
- 3-Bromo-2,6-dichloropyridine ha e qhibilihe ka metsing, empa e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide (DMF).
Sebelisa:
- 3-Bromo-2,6-dichloropyridine ke motsoako oa bohlokoa oa organic synthesis bohareng, o sebelisoang haholo indastering ea chefo e bolaeang likokoanyana, ea meriana le ea lik'hemik'hale.
-E ka sebelisoa e le lisebelisoa tse tala bakeng sa motsoako oa metsoako e meng, joalo ka chefo e bolaeang likokoanyana, lithethefatsi tse khahlanong le mofetše le lidae tsa fluorescent.
Mokhoa oa ho itokisa:
Tokisetso ea -3-Bromo-2,6-dichloropyridine e ka fumanoa ka ho itšoara ka 2,6-dichloropyridine ka bromine.
-Maemo a karabelo a hloka ho futhumala 'me a etsoa ka solvent e loketseng e kang acetone kapa dimethylbenzamide.
Lintlha tsa Tšireletseho:
- 3-Bromo-2,6-dichloropyridine e lokela ho bolokoa ka mokhoa o thibelang lerole le ho bolokoa sebakeng se pholileng, se omileng, hole le mollo le mocheso o phahameng.
-Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka likhalase, liatlana le liaparo tsa ho itšireletsa ha u sebelisoa.
- Qoba ho kopana le letlalo, mahlo le tsela ea ho hema. Haeba ho ka etsahala hore u kopane ka phoso, hlatsoa hang-hang ka metsi a mangata 'me u batle thuso ea bongaka.
-Ha o sebelisa le ho boloka, ela hloko ho latela mekhoa e nepahetseng ea ts'ebetso ea ts'ireletso ho netefatsa polokeho ea botho le polokeho ea tikoloho.
