3,4-Dibromopyridine (CAS# 13534-90-2) inosanganiswa nemakemikari ane C5H3Br2N. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzira uye ruzivo rwekuchengetedza:

Zvakasikwa:
3,4-Dibromopyridine haina ruvara kune yakachenuruka yero yakasimba uye inonhuhwirira yakasarudzika. Inonyungudika mu organic solvents senge ethanol, chloroform uye dimethylformamide pane yakajairika tembiricha. Inoratidza nzvimbo yakakwirira yekunyungudika uye kuvira.

Shandisa:
3,4-Dibromopyridine ine zvakakosha zvinoshandiswa mune organic synthesis. Inogona kushandiswa senge inokonzeresa kana kuita yepakati kutora chikamu mune dzakasiyana siyana organic reactions, senge Suzuki coupling reaction, C-C bond formation reaction, nezvimwe. Pamusoro pezvo, inogona zvakare kushandiswa mukugadzira zvinodhaka, dhayi uye. polymer compounds.

Kugadzirira nzira:
Nzira yekugadzirira ye3,4-dibromopyridine iri nyore. Imwe nzira yakajairika ndeyekuita pyridine nebromine pasi pemamiriro akakodzera ekuita kuti ibudise 3,4-dibromopyridine. Maitiro acho anogona kuitwa pane yakajairika tembiricha kana pasi pekudziya.

Zvekuchengetedza
Kuchengetedza kuchengetedza kunodiwa pakubata 3,4-dibromopyridine. Inogona kukonzera kushatirwa kana kukanganisa maziso, ganda, uye kufema system. Naizvozvo, midziyo yekudzivirira yakakodzera senge magirazi ekuchengetedza, magirovhosi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekushanda. Dzivisa kufema mhute yaro, uye zviri nani kushanda munzvimbo ine mhepo yakanaka. Pakurasa marara, cherechedza mitemo yenzvimbo uye uirase nemazvo. Kana iwe uine chero hutano kana kuchengeteka kunetseka, iwe unofanirwa kukurumidza kutendeukira kune nyanzvi.
