Mawu Oyamba
2-cyano-3-fluoropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 2-cyano-3-fluoropyridine:
Ubwino:
- Maonekedwe: Makristalo oyera mpaka owala achikasu kapena ufa wonyezimira.
- Kusungunuka mu zosungunulira zambiri organic kutentha firiji.
Gwiritsani ntchito:
- 2-Cyano-3-fluoropyridine nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic. Itha kutenga nawo gawo pazosintha zosiyanasiyana, monga kulowetsa, condensation, ndi cyclization, kupanga ma organic okhala ndi zinthu zosiyanasiyana.
Njira:
- 2-Cyano-3-fluoropyridine nthawi zambiri imakonzedwa ndi kaphatikizidwe ka mankhwala. Njira yodziwika bwino ndikuchita 2-cyano-3-chloropyridine ndi silver fluoride (AgF) kuti ipange 2-cyano-3-fluoropyridine.
Zambiri Zachitetezo:
- 2-Cyano-3-fluoropyridine imakwiyitsa khungu ndi maso, ndipo iyenera kutsukidwa ndi madzi ambiri mutangokhudzana.
- Kukoka mpweya wa fumbi kapena mankhwala kuyenera kupewedwa mukamagwiritsa ntchito komanso pogwira. Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino ndikuvala zida zodzitetezera zoyenera monga magolovesi ndi magalasi.
- Sungani kutali ndi moto ndi okosijeni.
- 2-Cyano-3-fluoropyridine iyenera kugwiritsidwa ntchito ndikutayidwa motsatira njira zotetezera. Pakachitika ngozi iliyonse, njira zadzidzidzi ziyenera kuchitidwa nthawi yomweyo ndipo upangiri wa akatswiri uyenera kufunsidwa.
