Mawu Oyamba
2,4-Dibromopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 2,4-dibromopyridine ndi kristalo wopanda mtundu kapena wopepuka wachikasu.
- Kusungunuka: 2,4-dibromopyridine imasungunuka mu zosungunulira zambiri za organic monga ethanol, dimethyl sulfoxide ndi chloroform.
Gwiritsani ntchito:
- Utoto: Ndi utoto womwe umagwiritsidwa ntchito nthawi zambiri womwe ungagwiritsidwe ntchito kupanga utoto wamitundu yosiyanasiyana.
Njira:
2,4-Dibromopyridine ikhoza kukonzedwa ndi njira zotsatirazi:
- Catalyst bromination: Pansi pa zinthu zamchere, 2,4-dibromopyridine imatha kupezeka pochita pyridine ndi brominating agent.
- Carbon-deuterium chiral halogenation reaction: 2,4-dibromopyridine imapezeka pochita gawo lapansi ndi bromine.
Zambiri Zachitetezo:
Chitetezo ndi kugwiritsa ntchito 2,4-dibromopyridine ziyenera kuwonedwa motsatira mfundo zotsatirazi:
- Gululi ndi lapoizoni ndipo liyenera kugwiridwa mosamala.
- Zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitchinjiriza ziyenera kuvalidwa pogwira ndikugwiritsa ntchito.
- Pewani kutulutsa fumbi lake kapena kukhudza khungu ndi maso.
- Izi zigwiritsidwe ntchito pamalo olowera mpweya wabwino komanso kupewa kukhudzana ndi moto kuti zisapsa kapena kuphulika.
- Njira zoyendetsera ntchito zotetezeka ziyenera kutsatiridwa panthawi yogwira ndi kusunga.
