Mawu Oyamba
3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
1. Chilengedwe:
- Maonekedwe: 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine ndi yolimba yopanda mtundu mpaka yotumbululuka.
- Kusungunuka: Kumasungunuka m'madzi, koma kumasungunuka mu zosungunulira monga ether, methanol ndi methylene chloride.
- Chemical properties: Ndi gulu la alkaline lomwe limapangitsa kuti ma acid azitha kusintha. Itha kugwiritsidwanso ntchito ngati reagent fluorinating kuyambitsa magulu a trifluoromethyl mumagulu ena achilengedwe.
2. Kagwiritsidwe:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl) pyridine amagwiritsidwa ntchito popanga organic synthesis reaction monga chothandizira kapena reagent. Mwachitsanzo, itha kugwiritsidwa ntchito popanga ma bond a carbon-fluorine ndi ma amination reaction.
- Itha kugwiritsidwanso ntchito ngati choyambira kapena chapakati pakuphatikizika kwa mankhwala.
3. Njira:
- Njira yokonzekera yomwe imagwiritsidwa ntchito kwambiri ndikuchita pyridine ndi trifluoroformic acid ndi sulfuric acid kupanga 3-chloro-2-hydroxy-5-(trifluoromethyl)pyridine.
4. Zambiri Zachitetezo:
- 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine iyenera kupewedwa posungirako ndikugwiritsanso ntchito pokhudzana ndi ma okosijeni amphamvu ndi zoyaka moto kuti apewe moto kapena kuphulika.
- Zikhoza kukhala ndi zotsatira zokwiyitsa pakhungu, maso, ndi kupuma, ndipo zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zipangizo zotetezera kupuma ziyenera kuvalidwa pogwira ntchito.
- Mukamagwiritsa ntchito kapena kugwiritsira ntchito pawiri, ziyenera kuchitikira pamalo abwino komanso kupewa kupuma kapena kumeza mwangozi. Pambuyo pa chithandizo, malo okhudzidwa ayenera kutsukidwa bwino.
