Nhanganyaya
2,4-Dibromopyridine is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
- Kuonekwa: 2,4-dibromopyridine isina ruvara kana chiedza yero crystalline yakasimba.
- Solubility: 2,4-dibromopyridine inonyungudika mune zvakawanda organic solvents senge ethanol, dimethyl sulfoxide uye chloroform.
Shandisa:
- Dhayi: Inowanzo shandiswa dhayi yepakati inogona kushandiswa kugadzira madhayi ane mavara akasiyana.
Nzira:
2,4-Dibromopyridine inogona kugadzirwa nenzira dzinotevera:
- Catalyst bromination: Pasi pemamiriro e-alkaline, 2,4-dibromopyridine inogona kuwanikwa nekuita pyridine neine brominating agent.
- Carbon-deuterium chiral halogenation reaction: 2,4-dibromopyridine inowanikwa nekuita substrate ne bromine.
Zvekuchengetedza
Kuchengeteka uye kushandiswa kwe2,4-dibromopyridine kunofanirwa kucherechedzwa zvinoenderana neanotevera mapoinzi:
- Mushonga uyu une muchetura uye unofanirwa kubatwa nehungwaru.
- Midziyo yekuzvidzivirira yakafanira senge magurovhosi, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekubata nekushandisa.
- Dzivisa kupinza guruva rayo kana kusangana neganda nemaziso.
- Inofanirwa kushandirwa munzvimbo ine mhepo inofefetera uye kudzivirira kusangana neinodzima moto kuti isabate moto kana kuputika.
- Nzira dzakachengeteka dzekushanda dzakachengeteka dzinofanira kuteverwa panguva yekubata nekuchengetedza.
